Fireman

A guy meets a childhood pal: "What are you doing with yourself these days?"

"I'm a fireman," replies the friend.

"Oh yeah? My 15-year-old kid wants to be a fireman."

"Well, if you want some good advice, you'll install a pole that will go to the basement so your kid can practice, 'cause the hardest thing for a fireman is to jump off into space and catch that pole in the middle of the night."

Ten years later, the two guys happen to meet again.

"Well, did your son become a fireman?"

"No, but I have two daughters who are exotic dancers."
