Two fleas had an arrangement to meet every winter in Miami for a vacation. Last year when one of the fleas gets there, he is shivering and shaking.
The other flea asks, "Why are you shaking so badly?"
"I'm freezing, because I rode down here from New Jersey in the moustache of a guy on a Harley" he says.
The first one says "that's no way to travel; do what I do.  go to the New JerseyAirport bar and find a nice stewardess, crawl up her leg and fly down here in comfort."

A year goes by and pretty soon the first flea shows up shivering and shaking.

"Didn't you do what I told you?" asked the second flea.

He replied "I did exactly what you said.  Went to the airport bar, found a nice young stewardess, crawled up between her legs and fell asleep.  Next thing you know I'm back in the Harley guy's moustache heading for Florida."
