We’d like to thank Ali for sharing this story:
One time, I was sitting in the Intelligentsia Cafe by my house, struggling with a really involved proof that I just couldn’t get right. I’d been working for hours, looking pretty haggard and stressed out, not noticing anything or anyone around me, when suddenly someone leaned over me, snatched my pencil, wrote “converges to 1/e” near the middle of my work, crossed out everything below it, then wrote “QED”. Shocked (and elated, since it was true!) I looked up and saw Bill Murray staring down at me. “No one will ever believe you”, was all he said, and he walked away.
