Squirrel Comedian Hilariously Plays Possum

This is easily one of the most bizarre animal behaviors I have ever seen and most definitely the strangest behavior from a squirrel. You will definitely get the feeling that his squirrel is a comedian who works his playing dead shtick for maximum laughs. And when he gets bored with staying in the death mode, he performs a fresh encore for yet more laughs. This looks to be a flying squirrel, possibly domesticated, but I have most definitely never seen anything like this behavior in a squirrel before. Any animal behavior experts out there have an answer?
