Michael J. Fox (a possible reference to the activist of the same name) is one of Sam-I-Am's pets who appeared in the Dr. Seuss book Green Eggs and Ham. He gets chased away by a pack of dogs and a Goat in Dr. Seuss on the Loose.
He later sings a song with the dogs, a goat and a mouse.
In the Netflix TV adaptation, he is voiced by Tracy Morgan.
