Re: polluting the well.
Some years ago (and for several years) I had a local supermarket "loyalty card" with the name "B. Munchausen" and the address of the store I usually shopped at. Since I always paid in cash at that store, there would never have been any sort of cross-check. Once--in perhaps ten years--a clerk asked if I was related to Baron Munchausen. I just smiled. Never seemed to occur to anyone that the name was a complete giveaway that it was all a fabrication...
