After watching Friends reruns for the last 16 years I think It's hilarious to hear Matthew Perry/Chandler Bing/Benny play a role in which he has freedom to say any swear word he wants. *SPOILER* After Benny leaves and has his 4 men try to kill you, when you tell him on the intercom that his attack failed and then he responds with "WHAT THE F$%#!?" I almost made heavy pants when I heard that, I laughed so hard when I heard him say that. You don't picture a "clean comedy" type to swear like that. I'm sure that Matt loved doing this and the change of pace involved with it.
