Last June, when I was still working at Fox Television Studies I got to spend a decent chunk of time on set when we were shooting Marc Maron's pilot presentation.
Here's a cool picture I took one night. It was only my second time on a set (the first being a Community visit, which was a wildly different experience) and Marc was watching some playback of a scene he'd just done, providing us with just the sort of comedic commentary you would hope to get from Marc Maron.
I totally forgot about this until I was looking at old iPhoto pics (you can really spiral into deep nostalgia when you're procrastinating) and thought, "Oh, right! This was really cool. It's Marc Maron watching Marc Maron!"
