Paddy and the Curtains ...

Paddy met Mick in the street and Mick said: "Paddy will you draw your bedroom curtains before making love to your wife in the future?"

"Why?"  Paddy asked.

"Because," said Mick, "All the street was laughing when they saw you making love yesterday."

Paddy replied, "Silly buggers; the laugh's on them. I wasn't home yesterday!"
