I love this dialogue from the ” Oil Wells” episode of I Love Lucy!

Ethel: You know, I think I’m going to like being a millionaire.
Lucy: Millionaire, millionaire…You know, I’ve said it so often it doesn’t mean much anymore.
Ethel: You know something?
Lucy: What?
Ethel: We might even get to be billionaires!
Lucy: Yeah, or even trillionaires!
Ethel: Or even zillionaires!
Lucy: Yeah, or even…what comes after zillionaires?
Fred: The income tax department!
