As a father to young kids, comedian and "SNL" cast member Bill Hader thought he was winning some cool dad points when he landed a guest spot on the popular Nick Jr. show "Yo Gabba Gabba." What he didn't realize, though, was that people are going to be asking him to do his dance for the rest of his life now.

So sure, he may have stopped by "The Late Show" Tuesday night to talk about his Emmy nomination or his new baby or the coming season of "SNL," but you better believe David Letterman didn't let him leave the stage without a taste of that "Dancey Dance."

Take notes, fellas.
