John Ratzenberger will always be remembered as Cliff from the long-running “Cheers”, but kids will recognize his voice for generations to come. He has lent his distinct voice to such animated features as Toy Story (1, 2, and 3), A Bug’s Life, Monster’s, Inc., Finding Nemo, The Incredibles, Cars (and its upcoming sequel), Ratatouille, WALL.E, and Up. He is the only actor to do voice work in all of Pixar’s films. And you can watch him on the dance floor on “Dancing With the Stars”, on which he made it to round 7.
