Used to be called Biffo (because of a ludicrous handlebar moustache I once affected), and for years I was known as Barmy (in the way the short men are called Lofty, black guys get called Chalky and red-heads Blue).
It didn't both me much, but my ex did get pissed off at being called "Mrs Barmy"!
The name still gets used by former colleagues and guys on my shoot - those who can't get their heads around my given name.
