Kinda like what Tad is saying, but a bit more general, interview a bunch of game designers and have them tell weird/funny/horrifying anecdotes and stories about their home sessions, be they recent or way in the past. Getting to hear Glancy or Jack Graham rant about past games sounds like comedy gold to me.
Getting to hear any games that the RPPR crew gets to play in, rather than run, would be cool, too. I know Ross and Caleb are gonna be all over the place between GMing, panels, interviews, and whatever booth time they may have to put in, but getting to hear their experiences with new games is awesome.
