What's your brush with greatness?

David Letterman used to have segment, “Brush with Greatness” where audience members told their (usually funnily ordinary) stories of meeting famous people.

What’s your brush with greatness?

Mine first.

I once sat down at a bar in Cambridge MA, and turned to see renowned architect Philip Johnson at my elbow. So I fancied myself as a bit of an architecture nerd, and I knew something about him. And I said I really enjoyed visiting a newish building of his, it’s in Chicago and I had customers there.

He said thanks. And asked if I was enjoying the weather in Cambridge.
