A boy and his date were parked on a back road some distance from
town, doing what boys and girls do on back roads some distance from
town, when the girl stopped the boy.
   
"I really should have mentioned this earlier, but I'm actually a hooker and
I charge $20 for sex."  The boy reluctantly paid her, and they did
their thing.
   
After the cigarette, the boy just sat in the driver's seat looking out the
window.  "Why aren't we going anywhere?" asked the girl.
   
"Well, I should have mentioned this before, but I'm actually a taxi driver,
and the fare back to town is $25."
