Three shelves of stuffed animals

A man and a woman meet at a singles' bar, and they quickly hit it off and decide to go back to her place. They immediately head for the bedroom.

Once in the bedroom, the man notices something peculiar: on the wall are three shelves full of stuffed animals: huge ones on the top shelf, regular-size ones on the middle shelf, and small ones on the bottom shelf. He doesn't have time to pay attention to them, of course.

After they have sex, the man says to the woman, "So, how was it?"

The woman thinks for a while and responds, "Eh, take one from the bottom shelf."
