There's no such thing as gravity, the Earth just sucks

In Spanish class, we took our final the penultimate class so that we would have time to do test corrections. During the block designated to taking the final (while we were doing test corrections) Sra. Riggs came in to do some end-of-the-year cleanup. She was trying to organize some cassette tapes when she dropped a large pile of them on the floor. David turned to me and said, "There's no such thing as gravity, the Earth just sucks." I didn't get it, so I went back to work and shortly thereafter asked, "Wait, when you said that, did you mean 'sucks' like (here I sucked in air quickly to make a sucking noise) or like 'is bad'?" He told me that that was the point: it was a pun. He then continued, saying that he wished real life were like a sitcom, in which people always answer puns with other puns. Sometimes these conversations can go on for a very long time. Unfortunately, as he now realized, this doesn't actually happen.

"It happens sometimes between me and Harvey," I said. "Well," I corrected myself, "they're not puns per se." What really happens is that I ask Him a simple question (let's suppose it's " Watcha doin'?") and He answers with something that is true, but does not answer my question in the least. In this case, it might be "Breathing." Then I do the same thing ("Watcha breathin'?") and so on indefinitely ("Air." "What kind of air?" ... ). As the responses get more and more ridiculous, trivial, and/or nonsensical, we both try to keep straight faces for as long as possible. I usually lose. OK, I pretty much always always lose. But I almost won one right before the end of the year...and I have all of next year to keep trying. Try it with someone you know (not Harvey...I call Him), it's fun!
