D'oh! Um, we mean... yay! Actor Dan Castellaneta will snag this year's voice-over Emmy Award for his work on The Simpsons. For 15 years he's been the voice of Homer, Krusty the Clown, Grampa and Groundskeeper Willie, among other animated characters. The honor will be presented at the technical Emmys on Sept. 12, a week before the televised trophies are doled out. Castellaneta previously won the same category in 1992 and 1993.
