Why would you pay $31k for a girl for one day? That's obscene. Reminds me of this scene from Gilmore Girls:

LORELAI: Seventy-five thousand dollars. Seventy-five thousand dollars. Oh my God, that’s like 150 pairs of Jimmy Choos.

RICHARD: What are Jimmy Choos?

LORELAI: Shoes.

RICHARD: 150 pairs, that’s it?

LORELAI: Dad, they’re Jimmy Choos.

RICHARD: For seventy-five thousand dollars, you should be able to buy at least three or four hundred pairs of shoes.

LORELAI: Not Jimmy Choos.

RICHARD: But that’s ridiculous. You are not going to spend seventy-five thousand dollars on Jimmy Choos when you could buy four hundred pairs of less prestigious but I’m sure equally stylish shoes. You will shop around first. Is that clear?

LORELAI: Yes, sir.
