...I tend to enjoy the 'celebrities' that don't spend much time in the lime light to begin with--they know their place and don't detract from that.
Bill Murray is one of the greatest actors of the last 30 years (any arguments are from those that have never seen Dead Flowers), and all you typically read from him is something funny he wore in a charity golf outing.
Every dude who was on Friends.
Uh, did you not see is awesome cameo in It's Always Sunny in Philadelphia?!?!
Was the other guy in Wham! ever really famous?
