Triumph the Insult Comic Dog has gotten neutered, but for a good cause: He's starring in a PETA ad - one that slams American Idol runner-up Clay Aiken. Aiken told Rolling Stone, "I think cats are Satan. There's nothing worse to me than a house cat. When I was about 16, I had a kitten and ran over it." Apparently it was an accident, but Aiken needs to up the training for media requests, while maintaining the whole "straight" training.

Anyway, Triumph wears a post-surgery collar and a bandage on his privates. Will any readers who watch MTV TRL (Gothamist loves TRL and woo-woo-ings -"Wooo!!! I wanna give a shout-out to my homies in Scarsdale!!!") let us know about Triumph's appearance today and if he mentions the neutering? Triumph will be premiering the video of "I Keed" from his CD, Come Poop With Me.
