I can't place that female Blood Elf dance either. It does seem very familiar. Not Thriller. Though that sort of clawing the air bit does seem like it. I wish I could place it.
I hope it's not from something so stupid that I'll feel bad about it seeming familiar, at least.
Strangly, I kinda like it. I like that she seems only like half into it and that it doesn't look slutty at all. Sure won't look good on top of a mailbox.
Thank god.
