Sexual Statistics Book

A businessman boards a flight and is lucky enough to be seated next to an absolutely gorgeous woman.

They exchange hellos and he notices she is reading a manual about sexual statistics. He asks her about it and she replies:

- This is a very interesting book about sexual statistics. It identifies that American Indians have the longest average penis and Polish men have the biggest diameter.

- By the way my name is Jill. What's yours?

He coolly replies:

- Tonto Kawalski, nice to meet you.
