The US Grand Prix has peaked. Let's all pack up and go home. Thank you Matt Le Blanc.
What's going on? Everyone's lost the plot. Daniel Ricciardo and Daniil Kvyat are out in the pit-lane dancing together. Is it a waltz? I'm not one for dance genres.
The engineers have resorted to entertaining themselves now.
One chap from Force India starts banging out some sick break dance moves.
We've really reached the depths of F1 qualifying boredom now.

“Much of the off-track chat this weekend has been about engines one way or another. Partly about the new plan to introduce cheap 2.2-litre engines and pincer the manufacturers politically (which we mentioned below), but also about Red Bull’s engine supply.
"They are pursuing three options - a Ferrari of one description or another, a Renault (probably unbadged) and Honda. McLaren has a contractual veto over the identity of any second team Honda supplies next season, and they want to use it to stop Red Bull getting the engine.
"And Honda F1 boss Yasuhisa Arai told BBC Sport on Friday that supplying Red Bull would ‘realistically be very difficult because it is late October’. Other sources say Honda is potentially up for it.
"In which case Ron Dennis would have to make a call on whether he wants to upset his engine partner - which is contributing a net $100m to the team a year in terms of budget.
"Whichever engine Red Bull end up with, team boss Christian Horner then has to convince boss Dietrich Mateschitz it is worth continuing in F1. If an uncompetitive engine was a stop-gap to something better (such as the 2.2-litre plan), Mateschitz would be happier. He does not want to just ‘make up the numbers,’ as Horner puts it.”

I'm more than happy to talk about Strictly Come Dancing while the rain continues. I thank you all for keeping me entertained during this dullest of times.

"I suspect if the people at Race Control were standing out in the rain they would make a quicker decision than from their nice comfortable position."

What's the greatest wet grand prix of all time? Let's have it - use #bbcf1 on Twitter to get involved.
That is some cracking ice-cream action right there.
Nico Hulkenberg tells BBC Sport: "Really happy with the balance in the car, felt really comfortable, there was some aqua planing in places but we were competitive.
"At the moment it is just not possible to race, we've just got to be ready and on the money when the call comes."

“If this carries on, qualifying will be on Sunday morning at 0900 (local time). However, if it cannot be run then, the grid will be decided on the times from final practice.
"In which case, McLaren will be kicking themselves. Fernando Alonso was fifth fastest and Jenson Button ninth after the first few laps of the session, but the team brought them in to make set-up changes, rather than just pounding round as almost everyone else did.
"By the time they got out, they had slipped down to 14th and 16th and the rain had intensified, removing any chances of improving. The team had thus thrown away with bad session management their only realistic chance of starting a race in the top six this year. A point, a little bird tells me, a not-very-happy Alonso made to the engineers.”
We started this live text commentary 88 minutes ago, and the only thing we've been able to talk about is rain and Daniel Ricciardo's jeans.
The TV to my right is showing Strictly Come Dancing... I'm so starved of action I'm tempted to describe Ainsley Harriott's jive.

"Lewis Hamilton timed his lap beautifully and it was a masterclass of how to drive in the rain."
Lewis Hamilton was superb in final practice, blowing everyone else away. And guess what, you can watch the highlights of that session right here.
The weather forecast for Sunday's raceday is better, but not great. Get the full report here in video form.
Why did Jenson Button take a wetsuit to Austin? And how did he get to the beach so quickly?
Red Bull's Daniel Ricciardo, wearing a pair of jeans and sipping a cup of tea, yells BBC Sport: "Unless the rain settles we're not going to run. If the rain continues it's just logic we won't run today. Even if it just drizzles we can't go out there. I'm sure we'll run tomorrow."
If you're just tuning in to read about some red hot qualifying action, you'll be disappointed to know that all we have is grey, tepid non-existent action.
That's because it's chucking it down in Austin.
The FIA have optimistically pushed qualifying back to 19:30 BST.
If there is no qualifying today, they could try and give it a go tomorrow morning before the race.
If that isn't possible, they will use the times from final practice to decide the grid - which would mean Lewis Hamilton would be on pole.
In the mean time, we may have to start talking about James Marsden again to pass the time (loyal readers throughout the weekend will know what I'm on about).
You can, it's true.
