Jimmy Kimmel, in clay? Apparently, the host of ABC’s Jimmy Kimmel Live didn’t mind what form he would take when he agreed to guest star opposite Kevin Nealon in Nick at Nite’s stop-motion animated series Glenn Martin, DDS. EW obtained this exclusive clip from Kimmel’s appearance on Glenn Martin, which is now in its second season on the basic cable network. Kimmel’s episode is expected to air later this year.

In this clip, Jimmy plays himself and is an old childhood nemesis of Glenn (Nealon) from summer camp. Kimmel agrees to return to camp in the present day to race against Glenn.

Kimmel will also chat about his cameo when Nealon stops by his late night show on Sept. 9.
