House congested. Four stones in the centre, two of each colour. One brick each left to slide..

Mike: Do the doping tests extend to the designers of Norway's curling outfits?

Great Britain with the hammer in this fourth end. Norway look to halt their progress with a blocker way out in front of the house. Like putting automatic gates at the end of your drive way. GB, though, are wise to it. They nip around to the side gate.

We also have the free dance section of the ice dance beginning at 01:00 GMT. Nick Buckland and Penny Coomes placed 10th in yesterday's short program. With 20 pairs taking part and each couple allocated about seven minutes, the GB team will not be on the ice until around 03:00.

I’m on my way to the mountains to watch Rowan Cheshire in the halfpipe final.

And there’s only one way to travel - on the disco bus!

It’s fair to say the Koreans are big fans of multi coloured lighting.

I was chatting to Cheshire’s coach, Pat Sharples, yesterday and he said she has got a bigger run than what she did in qualifying.

“If she nails it, she can definitely finish in the top six,” he said.

Remember, the women's ski halfpipe final begins in a little more than 40 minutes. GB's Rowan Cheshire will look for a medal in the 12-strong field.

Easy as you like for Thomas Ulsrud to give his side a couple with the final stone of the third end. GB won't mind too much, though. They stay ahead and will get the hammer back.

What GB are trying to do now is play with very few stones in play, which makes it very difficult for Norway to build anything up. That way they avoid conceding any high scores.

It feels like GB may already have this match won. It's incredibly difficult to see Norway coming from four down, even in those trousers. Great Britain have plonked one of their red rocks in the centre of the house. Two stones each to play...

Further suggestions on memorable sporting outfits include Manchester United's grey kit, Liverpool's white suits in the 1996 FA Cup final and the female cycling team that wore lycra to supposedly makes themselves look naked.

That one will sting a little for Norway. They had a chance to score two there but that fantastic final shot from Kyle Smith really turned that end completely on its head.

What a start that is for Great Britain.

That steal gives them a superb start.

Thomas Ulsrud, the Norwegian skip, makes a complete hash of his final stone to put GB further ahead. Ulsrud, the 46-year-old, is wearing those outfits better than his team-mates. He looks like he could pose in Burton's window. Or play James Bond. He's got a jaw like a set-square. Apparently he's been on Norway's answer to Come Dine With Me.

With the Norwegian trousers at the forefront of our minds, I am wondering what are the greatest outfits ever worn in sport? Any sport will do.

Cathy Freeman's bodysuit? Roger Federer's blazer? Any sweater worn in the Ryder Cup?

Two stones apiece left in this end. Two Norwegian yellows nearer the centre of the house. GB skip Kyle Smith, tall and lean, cleans his brick and aims to the left of the Norway boulder at the front...
