(Lucy shows the Mertzes a Geiger counter)
Ethel: What is that?
Lucy: It's a Geiger counter to hunt uranium with while we're up in Las Vegas.
Ethel: A Geiger counter?
Ethel: Now, Lucy, I thought when you asked Ricky if you could go uranium hunting he put his foot down.
Lucy: Oh, he put down so many feet I feel like I'm married to a Cuban centipede!
