A Frenchman, an American and an Australian are in a pub..

And the Frenchman says, "When I make love to my wife she’s in such ecstasy her body rises centimetres off the bed."

The American, not to be outdone, replies, "When I have sex with my wife she’s having so much fun she rises inches off the bed."

They both then look at the Australian and ask “what about you, what does your wife do when you have sex?”
The Australian replies “Well, when I finish having sex with my misses I wipe my cock on the curtains and she hits the roof!"
