There was this girl in one of my art classes who got kicked out of class for throwing an absolute tantrum because we had to draw a nude model. She screamed "Why can't we draw a man dammit!?" And the teacher had enough of her and sent her home.
The class stayed dead silent after that, so about an hour into drawing her, it was just too awkwardly quiet so I randomly said to the model, "I'm glad you're not a man dicks are too hard to draw right." And the class erupted in repressed laughter.
