Champagne, beer, wine, you name it. Players, celebrities, and revelers who happen across the Cup celebrate by drinking alcohol out of it. You'd take a few gulps too if you came across players partying with it. You've got to think after all, that's how it ended up at the bottom of Mario Lemieux's swimming pool in 1991, right?
Consider though, the cup has also supposedly been used as a chamber pot on several occasions. Once in 1940, when supposedly, Ranger Hall of Famer Lynn Patrick and teammates urinated on it. And The Star reported that Detroit Red Wing veteran Kris Draper's diaperless newborn daughter did exactly what you'd expect a diaperless baby would do in it:
"A week after we won it, I had my newborn daughter in there and she pooped in the Cup," said Draper. "That was something. We had a pretty good laugh. It was, well, clean it out. I still drank out of it that night, so no worries."
