While looking for something else entirely, I stumbled last night upon a Czech South Park site containing foreign-language versions of South Park clips.
For example, the Spanish, French and German versions of the "Uncle Fucka" song, or the French and German versions of "Kyle's Mom's a Bitch".
As amusing as they are, I still think the English version of "Uncle Fucka" is superior, as the other versions lack Terence's bemused "Hmmm!" (or is it Philip's?) when the flatulence starts.
