Who were the two ambiguously gay guys Peggy invited on the train? I know I've seen them in another episode but my King of the Hill memory isn't as strong as it would be for The Simpsons or Family Guy.
A+ for the episode, strongest one of the block. I think the fact that KOTH is always seemingly not about to get another season pick-up is making the writers try extra hard to get that 'last season' just right, and since they keep getting picked up, that means they have to keep working harder to make the next season pretty memorable.
I also enjoy KOTH's emotional undertones that no other cartoon can really grasp at FOX. When Peggy was sad, sure, I didn't feel horrible, but I did understand that she was upset, unlike Family Guy where it just feels sort of weird (but Brian's episodes usually buck this trend) or The Simpsons where sometimes it works, and sometimes it doesn't.
