Well, FOX don'T exist in german ( the joke in the simpsons about fox exist but not fox for self) or fox is "prosieben" But right, I hate youtubes new "copyright" rule. I miss the good old stuff befour this rule.
I know the history of the simpsons, remember one of the special episodes ( I believe episode 139 ), and sometimes in german "prosieben" show specials to the simpsons like this old shorts or a small dokumentary, and I hear sometimes the commentarys on the simpsons DVD. ^^
There's another one that was tacked in front of "You Kent Always Say What You Want", where Homer tries to take a family picture. And at the end, Bart ruins the last photo on the roll. (I had a shirt based on it, which I made as a pillow. It's in my gallery, if you want to see it. )
