Joan Rivers and Will Ferrell
Rivers once said, "You have to be careful of meeting your idols, because I met that Will Ferrell and he's an asshole." Ferrell later explained that at the Golden Globes, "a producer told me to go say hello to Joan while she was talking to Mike Nichols and Diane Sawyer, so I do, and Joan is like, 'Excuse me, do you know who you're interrupting?' and I'm like, 'Yes, they're very big important people.' She thought I was being a jerk."
