I can plunge a paper straw clean through a raw potato but you can't find paper straws any more, so.....
I can stick out my tongue and touch my nose. Well, no one said I couldn't touch it with my index finger.
I can write upside down and backwards. Or just backwards if you wish. Or just upside down, if you prefer.
I can hide my eyes while you hold one of your arms up in the air with the other down by your side, then put both of your hands out and I can (uncover my eyes) and tell you which you held over your head. (such a no brainer!
I can make an origami bird with flapping wings.
I can recite "Said the Rose", by George H Miles. Well, not any more, but at one time.http://www.mochinet.com/recitals/rose.html
