I'll give you a good coach one. When we played NC State sometime in the mid-80's, Jim Valvano was on the sideline giving the refs an earful. The crowd shouted "sit" "sit" "sit" -- so he sat on the floor at the corner of the coach's box, criss-cross-applesauce, still giving the ref an earful.
I want to say I saw him do a lay-up with his team in warm-ups one of those games, too, but I may not be remembering it correctly. I'll blame the distance of time for that.
