The final GOMP of the night was the best moment.
Caller: "Hey Tom!, I don't want to take any time away from you and Marc Maron!"
Tom: "ok then" *hangs up*
Marc: *laugh* "OK, Tom, when you do that to them, what do they say?"
Tom: "I dunno. Sometimes they say it's an honor to be hung up. Sometimes they get upset. I dunno."
..you could detect the grin in the last quote, even though I'm seriously paraphrasing it. But I liked how relaxed Marc was able to get Tom on his own show. Certainly a rarer occasion.
Another different great moment personally for me was Jen Kirkman. I'd be happy if she called on any show, but this one? I didn't expect Marc to get all excited and ask her how the Seattle show last Saturday was. I was one of the FOTS at her show. Was Jen really nervous about that show for any reason? because she killed it that night. Either way, Jen gave a love shout-out to the Seattle FOTs, which I didn't expect, and I blushed from afar.
