Pop parody king 'Weird Al' Yankovic is having a laugh at the top of the U.S. album chart after debuting his latest collection of comedy tunes at the top of the Billboard 200.

The 54 year old's new release, Mandatory Fun, has rocketed to number one, giving the star his first chart-topper.

Weird Al took to his Twitter account on Wednesday (23Jul14) to alert fans to the news, writing, "It's official. Mandatory Fun enters the Billboard album chart this week at #1. Wow. Wow."

He added, "If you'd told me 30 years ago this would happen, I never would've believed it. If you'd told me 2 Weeks ago, I never would've believed it.

"I'm so pleased everybody is enjoying the album, and I'm enormously grateful for everyone's support. Thank you, thank you, Thank You."

Mandatory Fun is Weird Al's 14th studio album, and features comedy takes on hits like Pharrell Williams' Happy (Tacky) and Robin Thicke's Blurred Lines (Word Crimes), but the highlight is his reimagining of Iggy Azalea's Fancy, which Yankovic has turned into a handyman anthem, called Handy.

He promoted the new album by releasing eight music videos in eight consecutive days, and recently hinted the new release may be his last: "I hate to draw lines in the sand and say this is absolutely the last album, but it sure looks that way. It's the end of my record deal."

Jason Mraz's Yes! debuts at two on the new countdown and rockers Rise Against enter at three with The Black Market.

Meanwhile, pop/reggae group Magic! land a second week at the top of the Hot 100 with Rude.

Iggy Azalea's Fancy and Sam Smith's Stay With Me are unmoved at two and three on the new singles countdown, while Ariana Grande's Problem and Am I Wrong by Nico & Vinz round out the top five.
