An 80-year-old widower felt in need of some female company and decided to make his first trip to London to engage the services of a lady of the night.
On his arrival he noticed one lady in particular and started flirting with her. The prostitute started becoming annoyed and said: "Get lost old man! You're ruining business!" "Pardon me madam but I was hoping to 'get some action' tonight." said the old man.
The lady replied:
"You've got to be kidding! You're too old! You're all finished." "What
did you say?" asked the old man. "You heard me -you're all finished,"
she snapped back. "Oh," replied the old man, "how much do I owe you?"
