You do a lot of great voices. Maybe one day you could do me.   -Jennifer Tilly

The Story: Mark was asked by producer Don Hahn to sit in for a sick Eddie Murphy at the table read for Disney's movie The Haunted Mansion. A table read is where the actors cast in a film or TV show get together for the first time to read through the script, before beginning filming. Mark sat and read Eddie's lines in the movie, in Eddie's voice. Afterwards, talking to the very beautiful and sensual Ms. Tilly, Mark didn't quite know how to respond to her double-entendre'.

What do you need me here for-you got this guy. I can go back to my hotel.  -Gilbert Gottfried

The Story: The comedian was on Mark's morning radio show in Miami, promoting his local comedy club appearance. Mark began imitating Gilbert while they were on the air. Gilbert was taken back by the impression and wondered why he had bothered to get out of bed to come in.

Oh, I have to see this. You, my friend, have chutzpah!  -John Lithgow

The Story: When DreamWorks brought Mark into the studio to sing for Eddie Murphy in the Shrek DVD's Karaoke Swamp Party, Lithgow was finishing his part, and they were introduced. When he heard Mark would be singing 'I like big butts and I cannot lie..' for Eddie, Lithgow was impressed.

You do a great Cheech, man.  -Tommy Chong

The Story: Tommy Chong was a guest on Mark's radio show, and Mark played around with him on the air, doing an impression of Cheech Marin. Chong thought it was fun (and offered to sell Mark a 'tobacco smoking device').

This guy does the best Pee Wee Herman I've ever heard.  -Howard Stern

The Story: An old one. In 1991, 'Pee Wee' was busted engaging in self-manipulation in an adult theater. Hilariously coincidental was the fact that at the time, the Divynyls had a hit song on the radio called 'I Touch Myself'. Mark recorded a spoof of it, and sent it to different radio stations. Stern played it madly for a couple of weeks.

Is that you, or the other guy?  -Nicole Murphy

The Story: According to two different L.A. recording studio engineers, both of whom said Eddie told them the story when Mark's name was brought up, Eddie and his wife were watching TV one evening and saw a Shrek and Donkey Wal-Mart commercial. Eddie's own wife couldn't tell the difference. It was Mark.
