I am an Indiana resident (who travels from time to time) and I have a gray-man who I've had since 2014. Sir Chewsiph Rodontus (or Chewy) was estimated to be a year old when I got him so I think he is about 8 years old now. His nicknames are ; potato, squish, mijo, monster, kangabunny, turd factory, sparky, chewy, chewsiph, rodent.
He's basically my only child but there are other household animals (cats) that are not allowed in his foyer area. He knows a lot of tricks, loves mazes and figuring out how to escape his confines. His worst habit is destruction for sure but he knows he is king and adorable so he gets away with it.
