Quote from Ray in The Skit
Ray: And finally this is how Lee and Stan might visit someone's home. "Ding-dong! Hello! Thank you for inviting us."
Debra: "Oh, Stan, isn't this a lovely house?"
Ray: "It certainly is, and you are lovely too, Lee."
Debra: "Oh, thank you, Stan. I love you."
Ray: "And I love you, Lee." Now, let's take a look at how Frank and Marie might visit someone's home, shall we?
Debra: "Do you think Raymond is home?"
Ray: "Let's find out."
Both: "Ba-boom!" [mime kicking the door down]
