Nicknaming is a time honored tradition at my school, and I was branded with the moniker "Stalin". This was because my first name is Joe and I once had the gall (this is a rather conservative area) to say that Communists aren't inherently evil, they just want to give a lot of power to the government, which usually ends up abusing it.
Another kid at my school has tons of nicknames, (his name is Chris) Gristles[sup]1[/sup], Christopher (emphasizing the christ), Christ, Gristopher[sup]2[/sup].
[sup]1[/sup]He mis pronounced Gris, or gray, in french and the teacher said, "Gristles?" really loudly, as if confirming that's what he said. The kid responded as if she had said his name, and voila! New name.
[sup]2[/sup] You should be able to figure it out.
