A guy has been asking the prettiest girl in town
for a date and finally she agrees to go out with him.
He takes her to a nice restaurant, buys her a fancy
dinner with expensive wine and on the way home he
pulls over to the side of the road in a secluded spot.

They start necking and he's getting pretty excited.
He starts to reach under her skirt and she stops him,
saying she's a virgin and wants to stay that way.

“Well, OK,” he says, “how a bout a hand job?”

“I've never done that,” she says. “What do I have to do?”

“Well,” he answers, “remember when you were a kid and
you used to shake up a Coke bottle and spray your
brother with it?”

She nods.

“Well, it's just like that.”

So he pulls it out and she grabs hold of it and
starts shaking it. A few seconds later, his head flops
back on the headrest, his eyes close, snot starts to run
out of his nose, wax blows out of his ear and he screams
out in pain.

“What's wrong?!” she cries out.

“TAKE YOUR THUMB OFF OF THE END!”
