Jack Black, Eric Stonestreet, Aisha Tyler Others "Tacky" in Weird Al's New Video

Weird Al promised a new music video a day for eight days straight in anticipation of his latest album and he is finally delivering. "Tacky" is the first song to get the video treatment and it's a parody of Pharrell's annoyingly fun single "Happy." Aisha Tyler, Margaret Cho, Kristen Schall, Eric Stone Street and Jack Black all lend there tacky hands to help sing the song.

Mandatory Fun is set to release on Tuesday, July 15.
