Weird Al Yankovic is kicking off a full week of new songs from his album Mandatory Fun, and the first one is called "Tacky". The song lampoons the hugely popular song "Happy" by Pharell Williams, and there's a decidedly colorful music video that goes with it. Big names like Jack Black, Margaret Cho, Aisha Tyler, Kristen Schaal, and others dance shamelessly towards the camera just like in the Williams original. As always, the lyrics have been twisted in an entirely new (and hilarious) direction.

If you haven't had a chance to check out Pharell's original music video, be sure to take a look first, and not just to get the joke; it's extremely well-done.

"Tacky" and the rest of Mandatory Fun is available on iTunes right now. Those that are diehard Al fans will no doubt take the dive, but everybody else, it's probably worth riding out the week until the other videos hit the web. How many of you guys are picking up Mandatory Fun?
