There were two flea friends that decided to go to Bike Week at  Daytona.

The first flea got there early and was lounging on the beach when the  second flea got there. The second flea was sniffling, sneezing and really  sick. The first flea asks him why he is so sick. The second flea says, "I  caught a ride in a biker's mustache on the way here. It was freezing, sleeting  and snowing." The first flea say, "Next year, do what I do. I go to a college dorm, crawl up the leg of a beautiful woman and catch a ride in her hair."

So  next year the first flea again arrives early. The second flea arrives later and  he is sick again - this year even worse. The first flea asks, "Why didn't you try what I told you to do last year?" The second flea says, "I DID - I crawled  up a beautiful woman's leg and was quietly waiting in her hair. The next thing I know, I was riding down the road in a biker's mustache again!
