I have always called my uncle uncle, even my mum and dad call him uncle. This was as long as when I was a kid. Now, my uncle has a wife and she calls him uncle. Even her sister's/friends/whatever's KIDS call him uncle. But he's my uncle!!! I always found this a bit funny :D What do you think?

Anyway, your uncle must be a pretty special person. Keep him close!!
The more I say uncle, the weirder it sounds...
uncle, uncle, uncle, uncle, uncle, uncle, uncle.
Try saying battery! It's meaning slowly diminishes the more it is said!!

Maybe it's just his nickname?
