Every week, Mark and Hal take IMPORTANT listener-submitted topics that everyone argues about (Should you put Ketchup on a Hot Dog? Which is the best Harry Potter Movie? Star Wars or Star Trek) and settles them once and for all. They've been joined by guests like Nathan Fillion, Wil Wheaton, Paul F Tompkins and John Hodgman to settles their debates. New episodes every Tuesday at 9pm PT on Maximum Fun (or wherever you get your podcasts).
