I just got a new addition to my family. I need a good name for him. He is a black smooth coat guinea pig. He has almost the same coloring as my rabbit Oz (the one in the picture) Except he has more Grey in his face making him apear like a old man.

I have thought of a few names for him, such as, Wizard (so it will be Wizard and Oz), sherman, hank, Rodney, Gus, Waldo. I would like to know what name from this list you like and suggestions are welcome
