Remember watching quite a few of them when WoW was still quite new. Illegal danish was a classic, and the most ambitious one I ever saw was a 90 minute long, or so where they fought against the Lich King (don't remember the name, but it was before WotLK because they didn't have the actual Lich King model) and they managed to "cure" him or something after fighting him inside Sapphiron's room in Naxxramas.
Are these still being made? They must be better than ever with the new models.
