Oh I think I know it! This scene was hilarious! Is it Jimmy chatting up the adventures of him and his new girlfriend in "Bob & Carol and Lois & Clark"? :

"So then Aurora pulls me into this maintenance duct for the subway, and we walk past all these rats and broken glass, and just when you think you're about to meet the Mole People, there's a Rave."

Clark: There's no such word as chumpy.
Lois: Sure there is. Someone's a chump, therefore he's chumpy!"
Clark: Try again.
Lois: Are you challenging me?
Clark: You bet your sweet little chumpy I am!
