A very funny guy -- really. Among other things he's the voice behind Triumph, the Insult-Comic Dog, a repeating character on the Conan O'Brien show. Outrageously funny.
Being someone who likes Conan's persona, surprisingly (perhaps) I've not heard of this obscure character.
I do not believe Smigel had as much to do with this one, given the additional credit screen with two new names, and the cartoon style being significantly different. Perhaps animators on loan from NARAL.
PS that's Triumphs trademark line.....not an insult per se.
Basically for Smigel, like the creators of South Park, nothing is sacred and everything is liable to be mocked. Christianity provides a big, easy target, though Clinton, gays and others are also in their sights.
