I can lick my elbow, gleek, wiggle my ears, touch my tongue to my nose and chin, do the tongue curling tricks, twirl the index fingers, and draw the 6 and 8 while making circles with my feet. I can also bend in all sorts of crazy ass ways and touch my thumb to my wrist both backwards and forwards. And "shake" my eyeballs. And my toes are something else - I can pick things up with them, wiggle only the top knuckle on individual toes, bend all down but the big toe (like a "thumbs up") and other things.

Plenty of people can do the "paralyzed ring finger" thing with the FIRST knuckle down. Can anyone do it with the second? (I sure as hell can't)

It's interesting that a lot of people seem to be able to do multiple things on the "impossible" list, while some can't do any.
