Harry and his wife are having hard financial times, so they decide she'll become a hooker.
She's not quite sure what to do, so Harry says: "Stand in front of that bar and pick up a guy. Tell him a hundred bucks. If you've got a question, I'll be parked around the corner."
She's not there five minutes when a guy pulls up and asks: "How much?"
She says: "A hundred dollars."
He says: "Shit. All I've got is thirty."
She says: "Hold on."
She runs back to Harry and says: "What can he get for thirty dollars?"
Harry says: "A hand job".
She runs back and tells the guy all he gets for thirty dollars is a hand job. He says okay, she gets in the car, he unzips his pants, and out pops a simply HUGE male unit.
She stares at it for a minute, and then says: "I'll be right back." She runs back around the corner and says breathlessly: "Harry, can you lend this guy seventy bucks?".
