One night a guy takes his girlfriend home. As they are about to kiss each other goodnight at the front door the guy starts to feel a little frisky. With an air of confidence , he leans his hand against the wall and smiling, he says to her, "Honey would you like to have sex with me?"

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

"Oh come on! Who's gonna see us at this hour?" he asks grinning at her.

"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 too risky!"

"Oh please, I love you so much!"

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

"Oh yes you can! Please?"

"No, no. I just can't!"

"I 'm begging you!"

Out of the blue, the light on the stairs goes one, and the girl's older sister shows up in her pajamas, hair disheveled, and n a sleepy voice she says, "Dad says to go ahead and have sex with him or can do it...or if need be Mom says she can come down herself and do it. But for heavens' sake, tell him to take his hand of the elfin intercom!"

Lol

Good one!

That's funny right there!
