I once jokingly suggested to out kung fu teacher that we go challenge the wushu guys down the hall (I'm in a club at a university). He told me that once upon a time, guys would sometimes come in to challenge them. More recently, we were just starting class, when a bunch of wrestling guys came in (we train in the wrestling room), and started doing their training on the other side of the room. As our teacher was trying to figure out how we'd do things since we didn't have the full room, as we normally do, I said to him, "Aw, c'mon - we can take them!" Oh, I'd make a bad sifu.
