Henderson's one of the funniest cartoonists around, not to mention a really nice guy, and he's up for an Emmy for his work on SpongeBob SquarePants. The show is nominated for Outstanding Animated Program (For Programming Less Than One Hour), and he's on the ballot for writing the "Clams" episode. So fingers crossed on that. I don't know if he gets to go onstage if the show wins, but if so, two words: SOY BOMB.
Congrats to Sam, and be sure to check out his stuff at Serializer.net!
