Betty: What happened to Fred?
Barney: Well, I know this sounds stupid, but Fred hit himself on the head with a bottle. He knocked himself cold.
Betty: Oh, dear. I'd hate to tell that story to Wilma.
Barney: What do you mean, Betty?
Betty: Well, I mean...I mean, think how embarrassed Fred would feel if Wilma found out.
Barney: Well...Uh...Maybe we can sneak him into his house and put him on his sofa and she'll think he's asleep.
Betty: Sneak him into the house? Well, that's like sneaking an elephant into a telephone booth.
