A guy goes into a crowded bar and, looking for a place to sit, spots a stool next an attractive young woman. He climbs on, looks her over, and, when she smiles at him, asks, "Can I buy you a drink?"

"A MOTEL!?!" she replies at the top of her voice.

"No, no," says the guy blushing and aware of eyes turning toward him. "I asked if I could buy you a drink."

She replies, "NO, I WON'T GO TO A MOTEL WITH YOU!"

Followed by catcalls and snickers, the guy retreats to a dark booth in a distant corner of the bar.

A few minutes later the woman comes over. She says, "I'm sorry if I embarrassed you. You see, I'm a sociology student at the university here, and I wanted to observe the reaction of people here."

The guy replies, "SIX HUNDRED DOLLARS?!?"
