To tell the truth, it's really not the best original story, but the jokes are still outstanding... like the asbestos or the pothole scene. Also has a lot hidden references to other movies or cartoons I like very much.
And at the end, Earl tells the not so hidden message to respect the government for its work. With the other message: „Do good things and good thing hapen – Do bad things and bad things happen” it gives you a good example how to live (wrapped with a real funny garnish)
I like this Earl episode, still way better then other shows around.
