It's common around here, but I can't answer why as each instance may be different. Some people are named Charles-chuck-Chucky-Chickie.

I don't know why for Frank or Joseph though. It doesn't have anything to do with chickens though. lol.

I read somewhere, book or article or somewhere, that he and Chuckie merlino had the Barracuda on his knees begging for his life before they banged him out. Rough.
