Taking it to a whole new level

A friend of mine in college told me about a professor whom he greatly admired. It wasn't for his intellect, but for the fact that he was ambidextrous. He'd stand in the middle of the chalkboard (this was in the "olden age" before whiteboards), put the chalk in his left hand, and begin writing. When he got to the middle of the chalkboard, he's switch hands and continue. My friend practiced writing with his "off" hand for a year, but could never master the art of writing clearly with either hand.

I wonder what my friend would make of this guy - a pitcher who throws equally well with either arm. Check it out!
