Last Fling

Two old men decide they are close to their last days and decide to have a last night on the town. After a few beers they end up at the local brothel.
The madam takes one look at the two old geezers (Art and Gary) and whispers to her manager, “Go up to the first bedrooms and put an inflated doll in each bed. These two are so old and drunk, I’m not wasting two of my girls on them. They won’t know the difference.”
The manager does as he is told and the two old men go upstairs and take care of their business.
As they are walking home the first man says “you know, I think my girl was dead!”
“Dead? says his friend, “why would you say that?”
“Well, she never moved or made a sound all the whole time I was loving her!”
His friend says “I think mine was a witch!”
“A witch?” says the first” “why the hell would say that?”
"Well " the first man replies “I was making love to her, kissing her neck and when I gave her a little bite on the neck, she farted and flew out the window!”
