    5. Herb Powell – “The Simpsons”

    As Homer Simpson’s “seldom-seen half-brother,” Danny starred in two classic Simpsons episodes, including the one that introduced us to “The Homer” — a concept car so awesome, it would go on to put Powell Motors completely out of business. According to the show producers, Danny got so into his voice acting that they ended up incorporating some of his actual gestures and facial expressions into the Herb animation.
