Buster is called Buster bear, Bubba bear, fuzzy butt, pain in the butt (only when he's in what my mom calls his demonic state, which is about 9 or 9:30 pm when he runs all over the house growling and barking at absolutely nothing like he's been taken over by demons) , PITA gets used in our house by my hubby, and my baby girl who is just learning to talk calls him Butter, it really doesn't sound like Butter but it's close!
