The photographers will appreciate this one.
Photographer to friend: I never told anybody this, but when I was young and poor and trying to get started, a kindly rich lady saw potential and backed me, supporting me for a few years until I could get established, and now I'm rich and famous. I saw her in the park the other day, she had fallen on bad times, she's a bag lady now, picking up aluminum cans.
Friend: What a wonderful opportunity. What did you give her?
Photographer: I gave her 1/64 at f8.
