At the end of their date, a young man takes the girl back to her home. He decides to try for that 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?"
Embarrassed, she replies, "Oh, I couldn't do that. My parents will see us!"
"Oh come on! Who's gonna see us at this hour?"
"No, please. I would just die of embarrassment if someone saw us."
"Oh come on, there's nobody around, they're all sleeping!"
"No way. It's just too risky!"
"Oh please, please, I like you so much!!"
"No. I like you too, but I just can't!"
"Oh yes you can. Please?"
"NO, no. I just can't."
"Pleeeeease?..."
Out of the blue, the porch light goes on, and the girl's sister shows up in her pajamas, hair disheveled. In a sleepy voice the sister says: "Dad says to go ahead and give him a kiss. Or I can do it. Or if need be, he'll come down himself and do it. But for crying out loud tell him to take his hand off the intercom button!"
