(old joke but still funny)
A man boarded an airplane and took his seat. As he settled in he
glanced up and saw the most beautiful woman boarding the plane.
He soon realized that she was heading straight toward his seat.
As fate would have it, she took the seat right beside his. Eager
to strike up a conversation he blurted out "Business trip or
pleasure?"
She turned, smiled and said, "business, I'm going to the Annual
Nymphomaniacs of America Convention in Chicago."
He swallowed hard. Here was the most gorgeous woman he had ever
seen sitting next to him and she was going to a meeting for
nymphomaniacs!
Struggling to maintain his composure, he calmly asked, "What's
your business role at the convention?"
"Lecture," she responded. "I am the lead lecturer where I use
information that I have learned from my own personal experiences to
debunk some of the popular myths about sexuality."
"Really," he said, "and what kinds of myths are there?"
"Well, she explained, "One popular myth is that African-American
men are the most well-endowed of all men, when in fact it is the
Native American Indian who is most likely to possess that trait.
Another popular myth is that Frenchmen are the best lovers, when
actually it is the men of Jewish descent who are the best. I have
also discovered that the lover with the "absolutely best" stamina
is the Southern Redneck.."
Suddenly the woman became a little uncomfortable and blushed. "I'm
sorry," she said, "I shouldn't really be discussing all this with
you.
I don't even know your name."
"Tonto," the man said, "Tonto Goldstein, but my friends call me
Bubba."
