Jim Ross Meskimen (born September 10, 1959) is an American comedian, impressionist, and actor, known for his work on the improvisation show Whose Line Is It Anyway? and as the voice of President George W. Bush and other politicians for the internet Jib Jab animated shorts. He voices Thom Cat, Neighbor John, and Stumpy in Random! Cartoons.
Meskimen was born in Los Angeles, California, the son of actors Marion Ross and Freeman Meskimen. Meskimen portrayed the father of Mary-Kate and Ashley Olsen's characters in the 2000 direct-to-video film Our Lips Are Sealed. He is a Scientologist.
