When I get an idea that I think might work for the show, and I call up, and the phone is ringing, and on the live feed from the iPod, with my phone still literally ringing in my ear, I hear Tom say "Hey it's Paul F Tompkins" or "Hey it's John Hodgman". Then Mike answers the phone and acknowledges my "Good timing on my part again, eh?"
It's happened 6 times in the last year!
To the listener's benefit, but still.
