Sometimes, very rare, the dub is actually better (yes, subjective, but still) than the original. E.g. I do find Fear and Loathing in Las Vegas in German absolutely hilarious, start to finish. Then I watched the english version - was I surprised how serious this is in original voice. It's an entirely different movie in its original tone.
"Wayne's World" in French is also a masterpiece. But it's been dubbed by very good people (called "Les Nuls") who understood the jokes and created appropriate ones instead of loosing them in translation when needed.
