It's 2 in the morning and the travelling salesman calls the front desk at
his motel and asks for some female company but with certain physical
characteristics.
"She's got to be taller than 6 ft. and weigh no more than 100 lbs.," he
tells the desk clerk. Thirty minutes later, there's a knock on his door and he
opens it to see a tall, lithe young lady.
"I'm here for your pleasure, sir," she says.
"What do you weigh and how tall are you?"
She replies, "6'2 and 97 lbs."
"Perfect," he says. "Now take off all your clothes and get down on all
fours on the floor."
As she does this, he walks to the bathroom door, opens it and ushers in a
big St. Bernard dog.
The dog looks at the girl and the girl looks at the dog and the salesman
says, "Now Fritz, do you see what you're going to look like if you don't
finish your damned dinner!?"
