Hm well depending on how evil your thoughts are...I'm product of Jesuit education, so I'm sure I've got more stories around depending on what kind of situation you're looking for. But here are my top three.

One of my friends in college, her name was Christina. And then it got shortened to Xtina. And then Xena, Warrior Princess. And then just Warrior Princess, and soon we had a battle cry for every time we saw her...I think she's finally starting to live it down, but I think it started to p*ss her off after a couple of years.
