In case you are wondering, I did not think about the unfortunate nickname before I named my dog. I actually named him before I got him/saw him. I was thinking about dogs, and I knew I wanted a large one. So I was wracking my brain for large-dog names, and unbidden, John "The Duke" Wayne came to mind, followed closely by the ambrosia of the south, Duke's Mayonnaise . It just seemed right somehow.
ANYWAYS...
