I caught some of the episodes during the marathon, but succumbed to a mid afternoon-ish nap (during Jaynestown unfortunately, which is one of my favorites). Surprisingly, while I was sleeping on the couch, my dad came in from working on his car and DIDN'T turn the channel! I woke up just a few minutes before the episode ended and noticed that my dad didn't get up until the show was over.
Usually if he finds me looking away from my show for more than 2 seconds he'll change it.
