Robin Williams Small Lips
Whenever actor Robin Williams and his tiny lips entered a room, I imagine the first reaction was, "Ahh shit this guy is gonna go on and on with a joke until we all get tired of courtesy laughing." Robin Williams was indeed funny but his so-called 'riffing' style of humor got really old really quick.
Robin Williams' pinched and squeezed mouth starred in many great movies, including Good Morning Vietnam and Mrs Doubtfire, and I thought he was funny. I just know that deep down his costars must have become really annoyed every time he started going off on his little comedy tirade. Just imagine if you really had to take a dump and Robin Williams suddenly walked in the room—you and I both know you'd be holding that sucker in for the next fifteen minutes.
