One night a guy takes his girlfriend home. They are about to kiss each other goodnight, but the guy is feeling a little horny. With an air of confidence, he leans with his hand against the wall and, smiling, he says to her ”Darling, would you give me a blow job?"

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

Him: "Oh come on! Who's gonna see us at this hour?"

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

Him: "Oh come on, there's nobody around, they're all sleeping!"

Her: "No way. It's just too risky!"

Him (horny as hel_l): "Oh please, please, I love you so much?!?"

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

Him: "Oh yes you can. Please?"

Her: "No, no. I just can't"

Him: "I beg you ... "

Out of the blue, the light on the stairs goes on, and the girl's sister shows up in her pyjamas, hair disheveled, and in a sleepy voice she says: "Dad says to go ahead and give him a blow job. Or I can do it. Or if need be, he'll come down himself and do it. But for god sake tell him to take his hand off the intercom..."

Here’s the original clip, it’s classic.
