A guy had been asking the prettiest girl in town out for a while. Finally she agrees to a date. He takes her to a nice restaurant and buys her a fancy dinner with wine.
On the way home he pulls off the road to a secluded spot. They start necking and he gets pretty excited. He starts to reach under her skirt. She stops him says that she is a virgin and wants to stay that way.
"Well, OK." He says, "How about a blow job?"
"EEEEyyyyeeeewwwww!" She screems, "I'm not putting that thing in my mouth!"
He says, "Well then, How about a hand job?"
"I've never done that before." She says, "What do I have to do?"
"Remember when you were a kid and you used to shake up a soda bottle and spray your brother with it?" She nods. "I'ts just like that."
So he pulls it out. She grabs it and starts shaking it. A few seconds later his head flops back on the headrest, his eyes close, snot starts running out of his nose and wax blows out of his ears. He screams in pain.
"What's wrong?" She cries out.
"TAKE YOUR THUMB OFF THE END"
