Hedges once picked up a girl in a bar.
"Hey, ya wanna ... sleep with me?" she asked him.
"Sure," he said. He was desperate and she wasn't fat or ugly.
"Let's go to your place," she said.
However, he was impotent and she had passed out, so they didn't fuck that night.
When Hedges woke up, he said, "I got a headache!"
She said, "Shit -- I got a HELL of a headache."
He said, "So ya don't wanna ..."
She said, "No. But -- can ya get me some aspirin for my headache? And some water to wash it down?"
He said, "Let's make a bargain."
Sometimes prostitution doesn't involve only money. It might involve such goods as a painkiller, some water to wash it down, and a glass.
