According to EW, Gardell will guest-star on Young Sheldon this season, playing the neighbor of the Cooper family, Herschel Sparks. If you recall, in the Young Sheldon premiere, Herschel's son, Billy Sparks, was introduced. He was the kid with the chicken who tormented Sheldon out in the yard.

Gardell is a veteran at CBS, having headlined every season of Mike and Molly. He has also appeared on New Girl, My Name Is Earl and Girl Meets World.
