I was in a production of Bye Bye Birdie in high school with Rob. He was the lead which was fitting because, as underclassmen, we looked up to him as one of the older, cool kids. (Pun intended)
There's a scene when Rob chugs a beer. Seeing as it's high school, they gave him a fake can to drink. However, on the night of the performance, Rob switched it out with a full can of real beer. Opened it on stage at the appropriate moment and proceeded to drink the whole thing. It was the 80's... the faculty was none too pleased but shrugged it off as a senior prank.
