Coop: Vajoina! releases Squeak as Watson misses his shot. Boos from the fans and the cheerleaders as an ump comes in and throws down a flag on the play Uh... No, that wasn't a gay joke, that was an Australian joke. Aw, aww!

Coop: Thanks dude. Hehuh...
Joey: Coop, what's a vajoina?
Coop: Uh... So uh, what seems to be the problem... with you, guy?
