Fillmore ! Episode 20 (S02E07) - Links in a Chain of Honor 

Cheng Liu Don’t forget curling. It’s actually kind of funny that one wasn’t worked in to the episode with the Canadians. The regular characters could have been scoffing at it, as if the weird sports that they play at this school are any less boring.

Now that I think about it, I don't recall seeing any baseball, basketball, or football teams at X. @@TBustah

There is a curling mention in the episode Nappers Never Sleep. And who the hell gave this video a thumbs down? That's messed up, this is a great cartoon lol
