the elusive, un-Googleable podcast

Have you ever had moments of frustration when there was something you were trying to find and you just couldn't find it, even with the aid of Google?

I've been having one of those moments for the past week or so, but I'm thinking someone might be able to help.

I'm trying to find a podcast I listened to sometime in the last 6 months or so...  It was a story about a man who discovered his love of impersonating other people.  He introduced himself at a party once as a political figure (I think), posed as a doctor in a town, even met his wife while impersonating someone (soon revealing his cover, which made her like him even more).  He would get caught often, jailed for some time, then would be released and would go assume a different identity.

I remember one anecdote in particular where it was revealed that he had been impersonating a doctor, but when he was caught, the townspeople defended him because he had done such a great job curing them of all of his ailments.

It is so frustrating to not be able to find this (audio) podcast.  So far none of my keyword searches have yielded the results.

UPDATE 1: after a week of searching, I finally just found the episode while typing this post:  The Memory Palace -- episode on Ethan Weinberg:  http://transom.org/?p=16011

What amazes me is that it was only by typing out my description of the episode that I was able to finally find what I was looking for.  It's not that often that it's so difficult to find something online, but when it was just a memory of a story without any unique keywords, I couldn't find it.  But now that I've found it, I thought I'd still share.

UPDATE 2 (7/12/12):  It's happened again.  I'm trying to find a podcast I remember in which Robert Krulwich (of WNYC Radiolab) talks about how he was amazed by how a kid erupted into singing a Bach or Mozart piece after [scoring a goal in soccer]?
