"Weird Al" Yankovic wrote a parody to Pharrell's number one hit "Happy" and you HAVE to watch it.

Some of our favorite comedic friends like Jack Black, Maragaret Cho, Aisha Tyler, and even Kristen Schaal are featured in this cameo-laden video that premiered on "Nerdist!"

Here some of our favorite lines from this video: "Can't nothing bring me shame".. "Because they're tacky!" LOL 

We promise they will be stuck in your head all day!

Remember to stay tacky everyone!!
