It’s easy to forget how great Weird Al is, but then every few years he comes back with a new batch of parodies, and you're like, Oh, yeah, this is what I've been missing. With a new album, Mandatory Fun, set to come out tomorrow, Weird Al intends on releasing one new video a day for eight days. First up is "Tacky," his delightful parody of Pharrell's "Happy." The video features lip-synching from Aisha Tyler, Margaret Cho, Eric Stonestreet, and Jack Black. If this isn't fun enough for you, just imagine Pharrell's smile when he sat down to listen to what Weird Al did to his song.
