Mine came when I was doing some living history of the 1840's. A good friend of mine is living history interpretor at the Museum of the Great Plains in Lawton, OK. One weekend they were having a rendevous to educate the public and I was volunteering. Some of the guys there asked me what my camp name was and I said I didn't have one. I bought a new clay pipe that friday and broke the stem several times while holding it in my teeth. By sunday the bowl was mighty close to my face and everyone in camp was calling me "Claypipe" and it stuck. Every time I go to the museum to help out, I am Claypipe to all.
