Not a whole song, but a lyric I always got a laugh out of, in one of the numbers from the show Carousel ("You're A Queer One, Julie Jordan"). Early on in the story the main female character Julie and her friend Carrie are gossiping, and Carrie's doing her best to get Julie to say whether she fancies Billy (main male character). But Julie refuses to be drawn, prompting this song, in which Carrie reproaches her:

Carrie:
You're a queer one, Julie Jordan
You won't ever tell a body what you think
You're as tight-lipped as an oyster
And as silent as an old Sahara spink!

[spoken]

Julie: Sphinx.

Carrie: What?

Julie: You spell it with an X.

Carrie: That's only when there's more than one.

Julie: Oh.


Love it!!!
