On Monday, Stewart made a brief appearance on "Full Frontal with Samantha Bee."
In the segment, Bee calls in Stewart for some advice. But before he can do that, she wants to know why there's a pony in the room.
Bee then asked Stewart to take the pony to his "massage farm."
"I'm pretty sure I heard you gave up show business to go and professionally massage livestock," Bee said.
After retiring from "The Daily Show," Stewart and his wife Tracey bought a farm in Middletown, New Jersey.
While he doesn't necessarily massage livestock, the farm's purpose is to rescue abused animals.
While his appearances are rare, Stewart hasn't completely left the spotlight: he returned to "The Daily Show" in December 2015, and this past May he appeared on "The Axe Files."
Known for his political satire, he only made one related jab on "Full Frontal."
"You're white. Are you voting for Trump?" Stewart asked the pony.
You can catch "Full Frontal with Samantha Bee" on Mondays at 10.30 p.m. on TBS.
