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. Things were getting hot and heavy when the girl stopped the boy.
"I really should have mentioned this earlier, but I'm actually a prostitute and I charge $20 for sex,"
The boy just looked at her for a couple of seconds, but then 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."
