While enjoying a drink with a mate one night, this bloke 
decides to try his luck with an attractive young girl sitting alone 
by the bar.  To his surprise, she asks him to join her for a drink 
and eventually asks him if he'd like to come back to her place. 

The pair jump into a taxi and as soon as they get back to her 
flat they dive onto the bed and spend the night hard at it. 

Finally, the spent young bloke rolls over, pulls out a
cigarette from his jeans and searches for his lighter. Unable to 
find it, he asks the girl if she has one at hand.

"There might be some matches in the top drawer," she replies.

Opening the drawer of the bedside table, he finds a box of 
matches sitting neatly on top of a framed picture of another 
man. Naturally, the bloke begins to worry. "Is this your 
husband?" he inquires nervously.

"No, silly," she replies, snuggling up to him.

"Your boyfriend then?"

"No, don't be daft," she says, nibbling away at his ear.

"Well, who is he then?" demands the bewildered bloke.
Calmly, the girl takes a match, strikes it across the side of her 
face and replies, "That's me before the operation."
