Undead boogy

Now you know me, I love undead bodypopping as much as the next guy, but I've got one question about the Beatfreakz music video for "Somebodies watching me" (the one with the midget Michael Jackson). When all the zombies rise from their graves, they're all dressed like they had just been to an 80's disco. Who in their right mind would bury their relatives like that? Unless it was a bus full of discoing orphans that went over a cliff, then I'd understand.
