I remember reading the article Mike V. wrote explaing how he got the nickname "Duke" and why he was going to start using it instead of Mike in his by line ...
Seems there was a dog involved in the story ... but if you want to use a nick name , go for it .
My brother is "Digger" , a friend is "Fishy" , kid next door is "Bugger" , my Uncle is "Nookie" , local politician is "Needle Nose" ...
... funny ... I never got a nick name , kind of fell left out !
