A man boards an airliner, takes his seat, and is pleasantly surprised to notice an attractive young lady sat next to him.
He introduces himself, "Hi, I'm flying to Vegas for a couple of day's relaxation. What takes you there?".
"Oh, well it's a bit embarrassing actually", she replies, "I'm a student and my dissertation is about the difference in sexual techniques across different nationalities. There's a conference in Vegas tomorrow on that topic".
"Wow, that sounds interesting!"
"It is, there are some fascinating facts that research has uncovered. For example, the most considerate lovers are men of the Jewish faith, and the best endowed race are the Native Americans"
"That is interesting. Oh, allow me to introduce myself, my names Tonto, Tonto Goldstein"
