Here's one for you - do professional players still shout out 'megs!' when they pull off a nutmeg?
Luis Suarez did David Luiz twice last week - one more tonight and he gets to keep him.
Get out the popcorn, those nachos with that weird yellow 'cheese', and a giant cup of fizzy pop. We want your team's season summed in a movie title.

Barcelona's players were wearing some extraordinary gear as they came in to the Nou Camp earlier on this evening. As Roy Keane says on ITV, "They look like they're coming in from their Christmas do!"
Super relaxed times for Barca. They played brilliantly well last week and if PSG are to keep this tie alive they will have to pull one very big rabbit out of their hat.
'It's not impossible for us to win 2-0' - the ever confident words of Bayern forward Thomas Muller yesterday as he discussed his side's chances of turning around a two-goal deficit.
Bayern were unusually sloppy in Portugal last week, gifting Porto all three goals in a shoddy display. But, as Muller says, a 2-0 home win will be enough tonight. Very doable.

Here's some tips on how to get the best sleep possible from elite sport sleep coach Nick Littlehales:
Begin a pre-sleep routine 90 minutes before bed - start turning off televisions, mobile phones and other electrical devices which give off bright light. (Unless you're reading BBC Football live text commentary - of course)
Have a shower prior to sleeping. Your body temperature will cool after coming out of the shower and ease you naturally into a state of sleep.
Drink a glass of warm milk before bed. Dairy products are rich in tryptophan, which aids the production of sleep-inducing chemicals serotonin and melatonin.
See - we've all learned something there. Namely why we can't get enough sleep...
Have we all had a two-hour nap this afternoon? No?
Me neither. But maybe we should have done. Now I mention it I am a bit tired.
A sports scientist for Real Madrid has told the BBC how Gareth Bale and co snooze their way through life at the training centre, as the importance of proper sleep hits home with elite athletes.
Apparently Roger Federer banks 10 hours a night - and he's got two sets of twins! He must live in his own flat. Living the dream.
If a player gets a second tournament booking today he'll be banned for the semi-final first leg as usual. But the Champions League has a new rule this season that sees you lose all your yellow cards once you reach the semis.
So nobody will face the Paul Gascoigne/Roy Keane/Michael Ballack scenario of missing the final with a late booking in the semi-final second leg. Unless of course they get booked in both legs.
Progress? Or pandering to the ill-disciplined?
Zlatan Ibrahimovic is a man who has won titles in the Netherlands, Italy, France and Spain - but his one year at Barcelona was widely considered a flop.
The Swede cost Barca an eye-watering £50m when he joined Barca in 2009, with Samuel Eto'o heading the other way.
His record was not so bad - he scored 22 goals in a single season - but the feeling was that he never fitted in and detracted, rather than added to, Barca's style.
He also clashed with then coach Pep Guardiola. Big time. In his book Zlatan revealed an outburst in the dressing room which contains fruity language not suitable for the BBC site.
"I'm not violent, but if I were Guardiola I would have been frightened," he said.
He also offered this gem of advice to Guardiola: "you bought a Ferrari but drive it like a Fiat."
Nobody has suggested It's A Wonderful Life yet. Or Happy Feet. What movie sums up your team's season?
Simon Liddle: Leeds United. The Italian Job. Not the good one, the awful remake.
Simon Hulsman: Groundhog Day - Liverpool
Jamie Mannell: Cowboys and Aliens for Arsenal. Starts a bit rubbish, but then goes BRILLIANT!
Martin: Newcastle - Titanic

It's a big night in the Football League with one match in the Championship, five in League One and one in League Two - with something at stake in almost every fixture.
Millwall, in the Championship relegation zone, visit Blackburn knowing that a victory will take them to within a point of Rotherham, who still face a possible three-point deduction.
Promotion rivals Preston and MK Dons are both in action in League One. Preston, one point ahead of the Buckinghamshire side, travel to Notts County, who are two points adrift of safety, while the free-scoring Dons host mid-table Doncaster. Meanwhile Leyton Orient can climb out of the relegation zone with a win at Rochdale - a result which would end the hosts' slim play-off hopes.
It's free entry for the only game of the night in League Two - and the fans are in for a thriller as fourth-placed Bury entertain fifth-placed Southend. A win will put automatic promotion into Bury's hands, as they will move a point ahead of Wycombe in third place with two games remaining.
Tears. Laughter. Tension. Drama. It's all here. We want you to sum up your team's season with the title of a movie. Here's a few already.
Paul Moore: Man City. Gone in 60 seconds. Says it all really!
Dec (a Doncaster fan): Men who stare at goats - basically what our players do while playing
Sam Breen: Oceans 11 - Watford - About to pull off the Championship heist after being written off.
Simon Meredith: For Southampton probably The Great Escape considering how many people thought we could be relegated!

PSG may start the night as huge underdogs, but boss Laurent Blanc will not settle for a lack of focus.
The French side have to score at least three times in the Nou Camp to go through after shipping three away goals last week.
Blanc said: "We know the task is extremely difficult. Our problem is that we have to score, but I do believe we will have plenty of chances to do so.
"We have nothing to lose and we hope to prove we are better than we were in the first leg.
"The result last week would have been the same with our without our injured players. I would love to have all the players available for the first and second leg, but that can't happen. We can't complain about that because Barcelona dominated the game in Paris.
"PSG are building a great club and Barcelona is already a great club. We know we are not here on a school trip, we also know Barcelona will want to win so we have to be strong and solid."
Shohan Sen, Kent: Barca have failed to score only twice at home in all competitions this season. Barcelona have only conceded three goals in a match twice this season, both scorelines of which will not be enough for PSG to progress. It will have to be third time lucky on both accounts for PSG or I'm afraid it truly is Mission:Impossible!

BBC Sport's Simon Stone: "It could be a significant evening for FC United of Manchester.
"Ten years after the club was formed by fans disillusioned after the Glazer family's takeover of Manchester United, FC United only need to beat Stourbridge in their Evo-Stik Premier League game to confirm promotion to Conference North, tier six of the football pyramid.
"It would be the fourth promotion in the club's history in a game that will be their last 'on the road'.
"Since their formation, FC United have played at a variety of grounds but the supporter-owned club are due to open their purpose-built stadium, which fans have raised a significant proportion of the £6.5m for, at Broadhurst Park next month when they will play Benfica in a friendly."
All is not lost PSG!
Teams have overturned a first-leg deficit to go through on 33 occasions in the Champions League. However, only twice - Ajax's win against Panathinaikos in the 1995-96 semi-finals and Inter's victory against Bayern in the 2010-11 round of 16 - has a side progressed after a home first-leg loss.
So you're saying there's a chance...
Matias X del Azar: Verratti back for PSG is key, probably even more than Zlatan. No nonsense from Barca with both Mascherano and Busquets. Don't think three goals is ever going to be on the cards tonight.

Last week, Spanish newspaper AS superbly based their match report of Barcelona's win in Paris on the film 'An American Werewolf in Paris.'
We enjoyed it no end, particularly this line:
"Barcelona showed PSG where the boundary of Europe's aristocracy lies. That is: 'You're very rich, fine, but that only goes so far. Now out of my way while I destroy you'. Oui Monsieur."
But what we want to know is which film title best describe's your team's season so far - and why?

Barcelona make one change from the first leg as right-back Dani Alves returns from suspension.
PSG have Zlatan back up front and Marco Verratti returns in midfield. David Luiz - who will be hopefully keeping his legs shut - replaces the injured Thiago Silva.
Barca XI: Ter Stegen, Alves, Pique, Mascherano, Alba, Busquets, Rakitic, Iniesta, Suárez, Messi, Neymar
PSG XI: Sirigu; Van der Wiel, Marquihos, David Luiz, Maxwell; Verratti, Cabaye, Matuidi; Pastore; Ibrahimovic, Cavani
Barcelona are bang in form - they've won 32 of their last 36 games in all competitions - and were in fine touch in Paris last week.
Neymar put them ahead from a Lionel Messi pass before Luis Suarez's delightful second-half brace, nutmegging David Luiz on both occasions.
However, a late, late Jeremy Mathieu own goal has given PSG a sliver of a chance. The tiniest, barely perceptible chance.
But a chance nonetheless...
