And I thought this was going to be about that Kurt Vonnegut one, where the old guy is sitting thinking and occasionally claps three times. MUCH later in the book you read:

Sally in the garden
Sifting cinders
Lifted up her leg
And farted like a man.
The bursting of her bloomers
Broke sixteen winders;
The cheeks of her ass went
(clap)(clap)(clap).
