My Dad's handkerchief mouse

I was at my parents' house today and my babysitter Jimmy from back in the day (as in the 70s!) who is also a dear friend of our whole family happened to stop by with his wife and kids. We got my Dad to do his "handkerchief mouse" which he's been doing for probably fifty years now, at least. It never ceases to entertain little kids and give us old farts a good laugh, too.
