Waitresses who want to model. Models who want to act. Actors who want to sing. Is anyone happy doing the jobs they're in? Whatever the case, the actor-turned-wannabe-singer seems to be one of the douchiest strains of these hybrids. Take Billy Bob Thornton. I had no idea that this guy was a singer, musician, and according to him in this cringe-inducing interview he did with his band the Boxmasters — a "music historian."

Whatever Billy Bob might be, he's officially Douchebag Supremo in my book. Why? He gets furious with the affable and patient interviewer Jian Ghomeshi because Jian introduced him as an actor. His reaction? He stonewalls all Jian's questions with, "I don't know what you're talking about." His band looks embarrassed and miserable, he looks crazy, the interviewer looks baffled, and if you could see me — I look like I want to throw my shoe at the computer. Ugh! Quit taking yourself so seriously, Billy Bob. (Click here if you're a masochist and want to see BBT in all his DB glory for like 10 minutes.)
