Morris moves into a nursing home. As he looks over the list of citizens living there, he realises there are three times as many women as men. He decided this is a good tome to make some money, so he posts a sign on his door "Sex for Sale".

The first night he has a knock on the door.

Sadie says: "What does your sign mean?"

Morris replies: "I'm selling sex."

"Well," say Sadie, "How much?"

Morris thinks slowly and replies, "I hadn't thought much about prices, but I suppose it will be $5 on the floor, $10 on the chair, $15 standing up, and $20 on the bed.

Morris is quite pleased when he sees Sadie reach in her purse and pull out a $20 bill.

"Oh, you want it on the bed?"

"No," says Sadie, "I'll have four on the floor thanks"!
