When you get bored of your own history, do you make up an alternate one?

I have chipped teeth and over the years, people have asked me about it over and over. It gets boring telling the same story over and over, so I started making up alternate stories just to see if people would find them credible. Lately, I tell both stories and ask people which one sounds more likely.

I’ll tell my stories later on, but first you. Does anyone else do this? Do you get bored of the same stories over and over? If so, what do you do? Are you able to remain polite to people, or do you do as I do sometimes, and just make something up? Have you done this on fluther? In either case, can you give us an example of something with both the real story and the fake story side by side to see if we can guess which is which?
