I fucking love King of the Hill, I don't get why so many people hate this. It's some of the most subtle, and brillaint satrire on TV right now.
I like the one where Hank has to go to traffic school and Chris Rock is the teacher. "you're mama is so ugly, it affects her self-esteem"
The one where Bobby is a Lama.
The one where they get drunk on tequila and then jump out of an airplane ('this is my urethra')
The one with Buckley's funeral, where Cahn makes the speech about the tigers and the strawberry, and Hank thinks it's rude that he told a joke at the funeral
Shit, there are too many funny ones to name, but I agree anyone with Cotton in it is great. I loved when he went to Japan. I hope there's more with Hank's brother.
