Weird Al Yankovic Sings About Underpants on Wallykazam

Musician, comedian and author "Weird Al" Yankovic will appear on Nickelodeon's literacy-focused animated series Wallykazam next week, and the video of his performance on the show has been made available online.

And, yes, he'll be singing about underpants. Like you do.

Rolling Stone has the first look and listen at Yankovic's "Wizard Jeff" teaching kids the word "underpants." 

"I asked my agent to get me as many voiceover gigs as possible where I get to repeatedly say the word 'underpants' - so Wallykazam! was a natural fit," Yankovic said.

"Weird Al" will guest on the episode titled "Mustache Day," which will premiere on Nickelodeon on October 28th at 10:30 a.m.
