Bill and John, in their 80's decided to visit the Madam for one last sexual encounter.
The Madam noticed Bill and John approaching, she quickly prepared 2 blow-up dolls, placing one in each room on the bed.
Bill and John told the Madam that "We are here for the last time".
The Madam sent Bill upstairs to the room on the left and John to the room on the right.
After an hour Bill and John left the rooms, paid the Madam and left.
Bill and John were very quiet until Bill said: "How was yours"?
John said, "I think she was dead".
John said, "How was yours"?
Bill said, "I think she was a witch".
John replied, "How did you know she was a witch"?
Bill said, "Well I got on top of her, bit her nipple, she farted and flew out the window."
