Crazy Ex-Girlfriend‘s Rachel Bloom rocked zits and a marching band uniform for her performance of “Teenage Dream” on last week’s episode of Lip Sync Battle, and Undateable star Brent Morin is going with a similar theme this week: In a clip from the upcoming episode, where he competes against costar Chris D’Elia, the comedian dons some nerdy gear for his rendition of the Jackson 5’s “ABC.”

“That was the cutest thing I’ve ever seen happen on this stage,” Chrissy Teigen comments in the clip. “And I was worried! I thought it might get porn-y. But it didn’t.”

See a sneak peek from Morin’s performance above, and watch Lip Sync Battle when it airs Thursdays at 8 p.m. ET on Spike.
