Mine is a bit silly really. My real name is Jack.
I have 2 daughters and I've always called their boyfriends Barry (even though none of them have ever really been called Barry), then I called them Bazza for short (I know, its no shorter really

). Anyway I finally got fed up with naming them all after each other so I stopped, however I missed Bazza, so I decided to call myself it instead...
How ridiculous can a full grown man get?
