Josh Gad will reunite with his old Back to You co-star, Ty Burrell, on Modern Family.

EW has learned that The Book of Mormon star will make a guest appearance as Kenny, a neighbor of the Dunphys who worships the ground that Phil (Ty Burell) walks stumbles on — and he’s made all decisions in his life based on what Phil would do. (Who here doesn’t?)

The episode will air sometime this fall. Modern Family returns to ABC for its third season on Sept. 21.
