An old man was passing through a red light area
when a prostitute sees him and says, “come lets have fun.”
The man, who is in his 80s, says “i wont be able to”
She says “come on, you will be able to”
He says, “no no i wont be able to”
She insists, “come darling you definitely will be able to”
After much persuasion the man agrees and they go inside. They then induldge in the most passionate sex the woman has ever seen. The man keeps on going for hours.
The prostitute driven crazy remarks, “you are so good at it, why were you saying you wont be able to?”
The man says, “madam, i wont be able to…..pay”
