"Weird Al" Yankovic is celebrating this week's launch of his umpteenth album, Mandatory Fun, with eight music videos to be released daily.

He kicks things off with "Tacky," his pitch-perfect take on Pharrell's "Happy." For the video, "Weird Al" got a little help from his friends, so watch for dancing appearances by Jack Black, Margaret Cho, Kristen Schaal, Aisha Tyler and Eric Stonestreet from "Modern family."
