Multi-Grammy Award winner Weird Al Yankovic is releasing "Mandatory Fun" on RCA Records, his first new album since 2011's "Alpocalypse, tomorrow." Alpocalypse, featuring the Lady Gaga parody "Perform This Way," entered at No. 9 on the Billboard Top 200, and was the highest debut of Yankovic's career. It was nominated for two Grammys, including Best Comedy Album and Best Short Form Video for "Perform This Way."

Yankovic will launch the new album by posting eight music videos in eight days, starting with "Tacky," his spoof of Pharrell Williams' "Happy," which debuted today on Nerdist.com. Featuring guest appearances by comics Jack Black, Eric Stonestreet, Aisha Tylor, Margaret Cho and Kristen Schaal, the video was shot on location at the historic Palace Theatre in downtown Los Angeles (the same space used as Julianne Moore's apartment in "The Big Lebowski.")

The clip was produced by Nerdist's Chris Hardwick, Seth Laderman and Johnny Wickham, offering a montage of clashing colors, socks-and-sandals, Jack Black's backwards sequin fanny pack and "Weird Al"'s litany of social faux pas. Said Hardwick: "Al has always been one of my idols. If you had told teenage me that I would one day not only be friends with him but also get to produce a video for him, my young brain wouldn't have been able to process it."

 Mandatory Fun includes parodies of "Blurred Lines" ("Word Crimes"), "Fancy" ("Handy"), "Royals" ("Foil") and "Radioactive" ("Inactive"), as well as style takeoffs on Southern Culture on the Skids ("Lame Claim to Fame"), Foo Fighters ("My Own Eyes"), Crosby, Stills & Nash ("Mission Statement"), Pixies ("First World Problems") and Cat Stevens ("Jackson Park Express").

The "NOW That's What I Call Polka!" medley features Al on accordion running through snippets of "Wrecking Ball," "Pumped Up Kicks," "Best Song Ever," "Gangnam Style," "Call Me Maybe," "Scream & Shout," "Somebody That I Used to Know," "Timber," "Sexy and I Know It," "Thrift Shop" and "Get Lucky." 

The video isn't even up on youtube yet, but you can see the video it at the nerdist.com, here
