They wear green spandex, kilts, pajamas and body paint.

They're covered in pins, and carry around brooms full of player signatures.

They host morning classes, doling out lemon gin early in the morning.

This year at the Brier, the fans aren't just taking part in the entertainment, they are the entertainment.

Take the Sociable, for example. The nine men from Alberta have arrived at Credit Union Centre every day wearing different costumes. From dark Blues Brothers suits, to red onesie pajamas, you can't miss these men as they wave signs in the air spelling out their key word of the week, S-O-C-I-A-B-L-E, encouraging everyone to take a drink. During the last draw of the round robin, they even convinced all the alternate players to sit, wave signs and share a round.

Another Albertan who has been catching eyes is Greg Rosgen, better known as Kaptain Koe. Decked out in long blue underwear, a cape, and a giant yellow foam hat, he has been leading the charge for Kevin Koe's Calgary rink.

"We're having fun," he said. 'We're getting fans going, getting the crowds going, why not? We're in Saskatchewan, you know, we're still waiting to see the first watermelon head here."

While watermelon heads didn't make an appearance, plenty of green was on display. The most visible group made an appearance on the first day in green, full-body spandex suits, with the Saskatchewan flag draped over their shoulders.

"We're dressed like this, just coming out to the Brier to get the crowd pumped up a little bit and make sure everyone has a good time, you know," said Dillon Wiebe, one of the green men.

Their antics didn't just stay in the stands, either. They spread onto the ice, where players also took part. One of the men even tossed a doughnut hole to Steeve Villeneuve, Team Quebec's lead, during a game. His skip, Robert Desjardins, was okay with it.

"If you want to keep curling growing you've got to make people love it," he said. "It's not a professional sport, it's an amateur sport, but we have to make it interesting to the crowd and that's fun."

One skip who is enjoying getting in on the action is Ontario's Glenn Howard, who ran to the stands for a round of high-fives after a last-rock win.

"It reminded me of a [Saskatchewan Rough]riders game," he laughed. "But the guys were great. They were loud but cheering for us. I was totally okay with it."

Another skip who is embracing the enthusiastic crowd is Newfoundland and Labrador's Brad Gushue. Despite a losing record, Gushue has spent a lot of time interacting with those in the stands. He gave both a jersey and his broom to young fans, and has blown kisses to the crowd on more than one occasion.

"They're having a good time," said Gushue. "Keep it up. The rowdiness, the noise, it's fun for us curlers!"

The players say they're looking forward to seeing what fans will do next, heading into the playoffs.
