We aren't quite sure what to think about Fred Armisen and Charlyne Yi's appearance on Nick Jr.'s Yo Gabba Gabba!.
We usually love to see our fave stars pop up on kids shows, but Fred is srsly creeping us out!
But maybe that's what they were going for. We're pretty sure this show is trying to appeal to stoners as much as preschoolers!
Last season Yo Gabba Gabba! guests that you might also see on Adult Swim included: Sarah Silverman, Weird Al, Jack McBrayer, Paul Scheer, Anthony Bourdain, as well as the bands Of Montreal, Black Kids and The Killers.
But none of them were as creepy as Fred!
