I don't remember in which episode, but Kramer says at one time about a girl he is madly in love with (I think it is the book store girl who he's trying to steal from Jerry):
"She can bring home the bacon, fry it up in a pan!" This is a refernce to a 1978 ad for "Enjolt perfume" and it continues: "And never, never, never let you forget you're a man."
It must be a reference to this, or is it a saying in America?
