This year, Adult Swim‘s tradition of April Fool’s Day pranks that are actually funny (what a concept!) was themed around Smiling Friends.

Created by Zach Hadel and Michael Cusack, the weird and wonderful animated series follows the employees at Smiling Friends Inc., which aims to make people smile. The first episode of season two premiered, but the prank was Adult Swim airing three episodes from season one, all remade with puppets.
