A guy meets a childhood pal: "What are you doing for yourself these days?"
I'm a fireman.
Oh yeah? My 15-year-old kid wants to be a fireman.
Well, if you want some good advice, you've got to install in your house a pole that will go to the basement so you 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."
