This is so great. Great job! Makes it a lot easier to bring those aforementioned short attention span friends into the FOT fold, as opposed to sending them a link of the regular archives with a note that says, "Check out the Marky Ramone call at about 2:15." Or some such.
I'd vote to Gem (heretofore, "Gem" can be used as a verb) the old Mets fan vs. Yankees fan bit w/Jon Benjamin & Matt Walsh (me thinks it was). Though, if we're going for stuff with universal appeal, that might not be a good one. I just identify a little too closely with a Mets fan who is most acquainted with the '86 lineup.
Also, I know that we should be making these suggestions directly to Martin, but Jesus invented internet message boards for a reason.
