You're sick of MC Hammer dance? I have Tunak Tunak Tun -.-
But i think Blizzard animators have better things to do, like in-game scenes, etc. (i mean those in the quests, like Thasarian's meeting with Lich King at the end of "Last Rites quest"). Those aren't in the best quality... voice of one character is lower than others', and there are big gaps between their pronouncement, while they should be immediately after each other.
