10. Sir Paul McCartney

Everybody knows, rock-and-roll legend hall of famer, Sir Paul McCartney who was part of the Beatles back in the 1960’s. What people don’t know is that he is a staunch animal rights activist, going as far as banning people wearing any leather products from entering his dressing room door. If he even gets a whiff of that pastrami sandwich you had for lunch, the vegan songwriter will apparently get worked-up and throw you out. Also, he requires that his dressing room be filled with 19 six-foot-tall leafy green plants and four six-foot-tall variety plants. Wow.
