What do you think of the name Duncan?

one of my friends has a big oafish newfoundland (a huge breed of dog, if you didn't know) named Duncan. So every time I hear the name, that's all I think of. Kids would DEFINITELY call him Duncan Donuts especially if, god forbid, he winds up being a little bit on the chubby side. Plus what kind of a nickname would the kid have? Dunc? Sounds funny. Keep working on him and be persistent. If all fails, fingers crossed it's a girl.
