Is the guy from 30rock the guy from Cat in the Hat the movie?

Yes, I remembered when I was very young n I use to watch cat in the hat the movie n in the movie the mother had a loussey boyfriend who liked to sit on the couch n not watch the kids, he looke just like the guy who plays as the boss in the show 30rock but a younger version but then again I could be wrong. But I think I'm right
