I'm sure it'll come back to me eventually, but it's bumming me out. I searched through my KotH folders and I can't even remember which episode it was, so that doesn't help. It may have been the one about Bill doing the military physical.
In the meantime, I'm transcoding and stitching all my episodes together and transcoding them to full season MP3s for an on-the-go KotH experience. When I travel to visit my parents, I fly and only bring my phone. I was putting a few seasons of video on my phone and playing in VLC through the flight and to go to sleep at my parents' house. I couldn't take more than 3 seasons of stuff and having those on as constant background noise meant a lot of repeats (not that I don't repeat these episodes constantly since there aren't new ones anymore).
These are getting cut down to 20% of the former file sizes, so I'll have room for lots of these if not all the seasons everytime I head out. I've got a 64 gig SD in my phone, but it's about fully loaded up with death metal (which I'm not about to get rid of because who knows where my fancy will be at any moment) so this is a good alternative; I hardly watch the episodes when I'm out of town, just have it on for the noise.
