At Nationals? Well... in the hotel on Wednesday night, our team captain tried breakdancing to the Mario Brothers theme, did something resembling a flip-like maneuver and fell flat on his arse in front of the room door, at which point our roommate opened the door into his skull after coming back to get a soda.
That's the best G-rated one I can think of.
(Though I'm sure my teammate Mike can top that with the Beatles incident on Thursday.)
