Jim Nabors - S1.E4

A young kid named Scooter applies for a job as a go-fer. When Kermit remarks that he doesn't even look like a gopher, Scooter explains that he'll go-fer coffee, he'll go-fer sandwiches, he'll go-fer anything. Kermit says he doesn't have the money to hire him, until Scooter mentions that his uncle owns the theater.
