Ben Stein then
Appearing in a single episode of Married With Children, Ben Stein plays a man called Thomas. Thomas appears to be some sort of greeting committee when Buck arrives in Doggy Heaven.
He’s dressed in a chicken suit and helps Buck choose what he would like to be reincarnated as. Sadly, due to the judge in Buck’s case being a cat, he ends up back with the Bundys again as their new puppy, Lucky.
