My department has worked with a particular sales rep from printing company for the last several years. We see or talk to him pretty often, and he's kind of a goofball so we've developed a camaraderie with him. He does things like call one of us and ask to be put on spearkerphone so he can tell us some groanworthy knock-knock joke. Or arrive at our office and make a dramatic entrance as the elevator is opening because he knows we can see the elevator on the security camera.

So he called my coworker yesterday and she told him that I'm pregnant. He asked to be put on speakerphone and said congratulations. "Oh," I said, "I thought you were going to tell a knock-knock joke about babies."

My other coworker piped up: "That would be a knocked-up joke!"
