It was Jim's birthday, and he was considered to be an "old man" by his friends standards. So, to liven him up a bit, Jim's friends decided to give him something special for his birthday. They bought him a hooker.
The call girl, as she preferred to be called, went to his house and knocked on the door. When Jim answered, she said "Hi I'm your birthday present!"
Startled, he asked "What am I supposed to do with you?"
"I'm yours for supper sex," she answers.
So Jim replied "Well, I'm 75 years old so I'll have the soup."
