Walking down the Avenue today, I saw a gray-bearded African-American guy. He had just finished asking somebody for change, and as he turned toward me I assumed he was about to hit me up next.

Instead, he made a throwing motion with his right hand, out of which flew a paper airplane. A good one, too. It banked upward over my left shoulder and landed well behind me.

I complimented him on this impressive feat of engineering. He grinned and said humbly, “Got caught in an updraft.”
