A helping hand

Harry and his wife are having hard financial times, so they decide that 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 that you charge a hundred bucks. If you got a question, I'll be parked around the corner."

She's standing there for 5 minutes when a guy pulls up and asks, "How much?" She says, "A hundred dollars."

He says, "All I got is thirty". She says, "Hold on," and runs back to Harry and asks, "What can he get for thirty?"

"A hand job", Harry reply.

She runs back and tells the guy all he gets for thirty dollar is a hand job. He agrees. She gets in the car. He unzips his pants, and out pops this HUGE ......

She stares at it for a minute, and then says, "I'll be right back." She runs back to Harry, and asks, "Can you loan this guy seventy bucks?"
