Having looked them up, I've seen "Dang Ol' Love" but all I can really remember about it are Bill's attempts to meet a woman by putting potholes in the street. After that scene, I'm drawing a blank.
"Patch Boomhauer" aired during a time when I had quit watching Fox Sundays for whatever reason. I know part of it was how bad the Simpsons had gotten. It was basically the anchor for my watching on Sundays. After I quit watching that, I just quit watching at all. It wasn't until Family Guy came back that I started watching on Sundays again and started catching up on the Simpsons and King Of The Hill again. I've caught up a little bit on the Simpsons through reruns, largely by pure accident that I happened to be watching, but I've never really caught up on the seasons of KOTH that I missed. I kind of regret it but then I've also heard that the last two seasons or so are actually seeing the show recover from a slump, a slump which I apparently missed, so maybe it was lucky that I didn't see those.
