Which celebrities/charactors can you impersonate
 

In the spirit of the Celebrity Look-Alike thread that's been going around, which celebrities/charactors can you impersonate?

Here are mine:
Archie Bunker
Don Pardo (announcer of Jeopardy! and Saturday Night Live)
Gilbert Gottfried
Old Man Periwinkle
Dave Chapelle (when he's being hyper)
Charles Nelson Reilly
Mase and Puff Daddy (NOT!--I tried to do a song impersonating their voices, but someone said I sounded like a foreign professor).
Burton Richardson (Arsennnioooooooooo Hallllllllllll!!)

In celebration of The Simpsons 300th Episode on Sunday night, I can imitate pretty much all of the main characters on the show with the exception of Marge and Maggie.

Michael Jackson
Master P...UHHHHHHHH
Ozzy Osbourne
Dr. Phil
Chris Rock....Gooooood lawd that's a lot of money!
Kermit the Frog

I can impersonate Jim Carrey *from his Ace Ventura movies* right down to the facial expressions. That's about it. Scares small children. :p

Ms Wong from Mad TV
Rosie Perez

The cast of South Park. My "Mr. Garrison" is legendary.
