Adam Devine is a busy man — a workaholic, some might say. And he just added another role to his resume: The star of Workaholics/host of Adam Devine’s House Party/occasional actor on Modern Family/voice of Pizza Steve on Cartoon Network’s Uncle Grandpa is lending his pipes to a character on American Dad, EW has learned.

Devine will play an announcer at a Langley Falls Karate Tournament, in which Steve and Snot square off against each other. He will also voice another character in the episode, which will be one of the first on TBS this fall, when the show moves to the cable network from Fox.

This season’s guest list includes Zooey Deschanel, Olivia Wilde, Alison Brie, Steve Yeun, and Kim Kardashian.
