Quote from Kramer in The Merv Griffin Show
Kramer: Jerry, what are you doing tomorrow? I want you to come by the set. Jerry: What about my "questionable material"? Kramer: Nope, we got a whole new format. Edgy, youthful... Plus, we got Jim Fowler! Jerry: Jim Fowler? The animal guy from Wild Kingdom is coming to your apartment? Kramer: Well, I practically raised his kids.
