Intercom

At the end of their first date, a guy takes the girl home. Emboldened by the night, the guy decides to try for the first kiss. With an air of confidence, he leans with his hand against the wall and, smiling, he says to her, "Darling, how 'bout a good night kiss?"

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 too risky!"

Him: "Oh please, please, I like you so much!"

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

Him: "Oh yes you can. Please?"

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

Him: "I beg you...."

Suddenly, the light on the stairs goes on, and the girl's sister shows up in her pajamas, hair disheveled, and in a sleepy voice she says, "Dad says to go ahead and give him a kiss. Or I can do it. Or if need be, he'll come down and do it. But for crying out loud, tell him to take his hand off the intercom button!"
