Statistics
A businessman boarded a flight and was lucky enough to be seated next to an absolutely gorgeous woman...... They exchange brief hellos and he noticed she is reading a manual about sexual statistics.
He asks her about it and she replied, "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 average diameter. By the way, my name is Jill. What's yours?"
He coolly replied, "Tonto Kawalski, nice to meet you."
