John Cusack
John Cusack isn't a very nice guy—in fact, the Sixteen Candles actor is actually hated by the entire city of Chicago. Cusack has an entire subreddit thread dedicated to interactions with him, and almost all of them are negative. He's often spotted riding his motorcycle around town, and sometimes flipping off those who recognize him. "Cusack annoys me to no end," one Redditor wrote. "I work at a Lube 'n Tire shop near River North. Sometimes John brings his cars in to get tuned up. He is far and beyond the typical annoying customer who wants to hover near you or stare while you do your work."
Mandy Moore
This beloved actress might surprise you with her prickly side. Moore accidentally bumped into someone while grocery shopping one day, causing him to spill his groceries all over the floor. Instead of helping the man to pick them up, she stood there and complained that he was wasting her time. Well, Mandy, if you'd helped to clean up the mess, it would have gone faster!
