The Passerby

[Rondy]

A man is walking past a house when a used condom comes flying out of the second story window and lands squarely on his head. Rather disgusted and absolutely furious, he goes up to the front door and starts pounding on it.
An elderly man opens it and asks him what caused him to knock so loudly.
The passerby asks, "Who's in your upstairs room?"
The elderly man replies, "I can't see how it's any of your business. Since, you must know, my daughter and my intended son-in-law are upstairs."
The passerby hands him the used condom and says, "Well, I just wanted you to know that your intended grandchild just fell out of the window!"
