Raised in Woodland Hills, CA, and the son of a hearing aid specialist who worked in geriatrics and a full-time housewife, Garrett began performing stand-up at various Los Angeles Comedy Clubs upon graduation from high school. Spending six weeks at UCLA before his fateful appearance on the Tonight Show, the young comedian later felt the wrath of that show's grudge after telling a joke that the talent booker had warned him against. Garrett has since never been invited back. Nevertheless he continued on strongly, opening for Frank Sinatra and soon finding roles in such popular television shows as Roseanne, The Fresh Prince of Bel-Air, Seinfeld, and perhaps most famously, Everybody Loves Raymond. Offering his voice to numerous animated features since his breakout in the early '80s, Garrett voice acted in family films like Casper (1995), A Bug's Life (1998), Ratatouille, Tarzan II, Garfield, Tangled, and Finding Nemo. Garrett has also appeared in several movies, like Music and Lyrics, The Pacifier, and Night at the Museum.
