Hee. We had a pet squirrel when I was a kid (his name was Boomer, because I found him outside "Dr. Thunder's Boom Room" at the local science museum). He only had half of a tail when we found him, so I guess some critter had grabbed him out of the nest, but then lost him. Anyhoo ...
He was a great pet (if stupid), but he H-A-T-E-D my mom's best friend, Lynne. Every time she came in the house, Boomer would launch himself at her and try to grab onto her face. He would be all spread-eagled (spread-squirreled?) on her face while she was screaming and slapping at her head. It scared the hell out of her, but it cracked us kids up.
She was the only one he ever attacked, but he freaked out quite a few visitors just by being a squirrel who lived in a house.
