Griffin signed on for an Internet TV show called "The 5th Quarter," produced by OBB Pictures which premiered on November 30th.
The show is part of Verizon's go90 series and features short sports mockumentaries featuring athletes, actors, models, and sports broadcasters.
After a stint as a 30-year-old child named "Cliff, Cliff" in the show's first season, Griffin stars as Sheldon King, one of the best race walkers in the world in an episode called "Born to Walk."
"That relationship was a cold call. I called him and pitched him the idea," said director Michael D. Ratner of how he was able to get Griffin to agree to the show. "He said "it sounds awesome." It's a domino effect. You get one of these big athletes to do it, and then everyone wants to do it."
The episode also stars Jimmy O. Yang, Hailey Baldwin and Kenny Mayne.
