Your Sunday Squirrel

OK, so this perfectly respectable-looking squirrel was skittering around Denny Park yesterday.  He was very photogenic, as you can see.  I gave him a peanut and this is what he did:

I mean, I've seen squirrels hang upside down on tree trunks before lots of times.  But I've never seen a squirrel do that - just kind of hang there.  I'd get woozy, but apparently he wasn't bothered.  Notice that his back feet are almost turned backwards.  Squirrels can do that.
