Wide range of animated characters from children to old men (and lots in between!)
Impersonations/mimics of several different voices such as "Reverend Jim" (Taxi TV series), "Cliff Claven" (from Cheers), Ronald Reagan, Pee Wee Herman, Casey Kasem, Sean Connery, among others as well as numerous animated characters (Simpsons supporting characters, Beavis and Butthead, Marvin the Martian, Fozzy Bear, Miss Piggy, Yoda and many more).
Very strong ability to mimic many different types of voices.
