No, Jeff Dunham has never appeared on America's Got Talent. You're most likely thinking of Terry Fator America's Got Talent Season 2 winner (2007), who performed a ventriloquism act, which featured quirky characters, dynamic impressions and hilarious comedy.
Jeff Dunham achieved his mainstream success in 2006, when, after years of resistance, Comedy Central changed course and decided to showcase Dunham's self-produced one-hour special, Arguing with Myself. The results were astounding. More than two million viewers tuned in to see the ventriloquist, prompting the network to book him again.
Dunham is now one of the world's top-grossing comedians. And his characters -- popular and controversial at the same time -- have inspired praise from his fans, and sharp rebukes from his critics.
