This came in the LittleZellers.com inbox today:
"Please let me know what you would prefer the little one to be called -- Randall, Randy, Charles, Charlie or R.C.????"
Actually, this has been a frequently asked question over the past several days.
Usually people are called by their first name, not the middle one. The common nickname for his first name, "Randy", besides being the preferred style of Randall's grandfather, is a bad word in most parts of the world. So while I suppose in a free country such as this one you may address my son as you see fit, his mother and I call him "Randall."

I prefer the "R" & "Zell" combined to say..."Rzell."
Root word Randall Zeller.
Form Rzell
Language - Ebonics
From - his uncle
Used in a sentence: What's up "Rzell?"
sounds like Rizzle
