I played a game of strip Trivial Pursuit with a young lass that I'd just started seeing. The girl was studying law & fancied herself as a bit clever...but I had a weird head for trivia.
10 minutes in, she was in her underwear & I hadn't taken anything off. 15 minutes in, I'd won the game, went out in sympathy with her & joined her
Being a fantastically competitive girl, she insisted on a rematch a week later.
