Friends

A man takes his girl out. On the way home he stops five miles out of town and tells her
he wants to fuck her. She refuses to put out so he . . . puts her out. She walks back.
The next night they go back out again. This time, though, he has the presence of mind to
go out of town 15 miles before he stops the car and again tells her he wants to fuck her.
She declines. Once again, she's put out of the car, and treks 15 long miles back home.
Third night they're out. 30 miles away from home he stops the car. "I wanna fuck you".
But this time she gives in. Rather enthusiastically, to tell you the truth. After the
humping and pumping, he asks her why she gave in finally.
She replies, "Look, for a friend, I'd walk five miles. I'd even walk fifteen miles. But
there's no way on earth I'd walk thirty miles EVEN to save a friend of mine from a case
of Herpes!"
