Every comedy bit I do now is a diamond-studded rainbow, so I can confidently reveal bits from my past that were cubic zirconia-scarred rainclouds. Here is a truly bitter lemon from my comedic days of yore:
You're always hearing the term crack whore. How come you never hear about a crack celibate? How do we know crackheads don't practice abstinence? Maybe they save themselves for marriage, we don't know! Because think about it, crack is not exactly a love drug like ecstacy. With ecstacy, you're hugging strangers and giving footrubs. With crack, you're talking to walls and stabbing leprechauns.
If you listen closely, you can hear the logic of this bit collapsing in on itself. This is a prime example of a fake bit; one where the comedian twists a self-explanatory term--EVERYONE KNOWS CRACK WHORES ARE CALLED CRACK WHORES BECAUSE THEY SELL THEIR BODIES FOR CRACK. NOT ONE PERSON IN THE HISTORY OF CRACK HAS EVER TAKEN IT TO MEAN ANYTHING ELSE. YET HERE COMES "COMEDIAN" MIKE TO THROW SOME HACKY SAND INTO THE FACE OF AN OTHERWISE CRYSTAL CLEAR EXPRESSION--so they can contrive a bit based on a clumsy misconstruing of said term. This method of contriving material was huge in the 80s, but it never goes out of style.
Comedy crowds lap up fake bits, which is why the crack whore bit was a solid staple for at least three years. I wrote it during a terrible dry spell, and remember feeling like a proud papa when I brought it to the stage for the first time. As you can see, it was a birth more unfortunate than Rosemary's Baby.
