Hunter S. Thompson (while he was on some sort of hallucinogen preferably)
Carlos Maussa (aka Gollum)
Ghandi
Ted Kaczynski
Jebus (the artist formerly known as Jesus)
Garey Busey
Scott Weiland (not the post rehab version)
Flava Flav
Jerry Falwell
The last one is a draw between X and Timothy Mcvay (maybe X provided he doesn't go too far with the witticisms)
