Hey, I thought I answered this one, too. Guess it was somewhere else. Anyway, to explain mine I have to explain my husband's, and I probably won't do as well as he could.
Anyway, he was given the nickname Captain Elephant in his early teens by a friend, I think. It referred to, well, I think we know what it referred to. So he's been Cap ever since. Everyone I know calls him Cap.
Well, when I decided to be a member here I was trying to think of something that would kind of link me with him. So I came up with Ellie! Get it? Captain Elephant and Ellie?
Well, I thought it was cute.
