8. Jules Winnfield (Pulp Fiction)
Don't get me wrong: Pulp Fiction is an incredible movie and Samuel L. Jackson's character is probably one of the coolest and most hilarious personalities brought to film, but you just would not want to split a beer with this guy. I mean picture yourself at the local IHOP - you two are enjoying pancakes and the waiter spills some coffee... suddenly he's spouting bible verses and popping people in the face in the middle of breakfast. Nothing is more unsettling during an IHOP run than watching your best friend murder fellow breakfast patrons. The only reason his friendship with Vince works because they're both deranged, argumentative, borderline sociopaths. Unless you frequently executed people for a deranged mob boss or were some sort of foot massage connoisseur, the relationship would just never work.
