One night  a young bloke takes his girlfriend home.

As they are about to kiss each other goodnight at the front door, he of course starts feeling a little horny,

With an air of confidence, he leans with his hand against the wall and broadly smiling he says to her,

"Honey, would you have 'rumpy pumpy' with me?'

Horrified, she replies, "Are you mad? My parents will see or hear us!"

"Oh come on! Who's gonna hear or see us at this hour?" he asks grinning like the proverbial cheshire cat,

"No, please. Can you imagine if we get caught?"

"Oh come on! There's nobody around, they're all sleeping!"

"No way. It's just tooo risky!"

"Oh please please pleeaassse, I love you sooo much!"

"No, no, and nooo. I love you too, but I just can't!"

"Oh yes you can. Pleeaasseee?"

"No,no. I just can't"

"I'm begging you...."

Out of the blue, the light on the stairs goes on, and the girl's older sister shows up in her pyjamas, hair dishevelled, and in a sleepy voice she says:

"Dad says go ahead and have blooody 'argy bargy' with him, or,...I can do it.....or...

....if need be, Mom says she can come down herself and do it,

"But for Gods Sake, tell him to take his blooody hand off the intercom!!"......
