I wish I could animate-- this kinda reminds me of the "Good Idea, Bad Idea" filler clips from Animaniacs.
And now, on to your regularly-scheduled broadcast.
Metal: Dirty sluts
Not Metal: Strippers/Prostitutes (unless they're dead... or unless you're into Hairspray "Metal")
Metal: Chrome or Black hardware on your bass
Not Metal: Figured wood pickup covers, gold hardware (unless it's on a black instrument, such as Cliff Burton's Aria Pro II SB Black-&-Gold)
Metal: A Christmas Tree (as Nathan Explosion explains "it's like having a rotting corpse in your room")
Not Metal: Presents under said tree-- unless said presents involve a severed head.
Metal: Being arrested for Assault & Battery
Not Metal: Being arrested for shoplifting at The GAP, Old Navy, American Eagle, Abercrombie & Fitch, or other sodomized-fratboy-wannabe store.
Metal: Giving the middle finger to Justin Bieber or Michael Buble
Not Metal: Giving the middle finger to Ozzie (if in the presence of metalheads, this will likely get you killed)
Metal: Celebrating a Dethday
Not Metal: Celebrating a Birthday
Metal: Wearing all Black
Not Metal: Wearing all Pink (unless you are a metal chick, at which point comes the expectation that any Pink worn is to contrast with Black)
Metal: Clowns that do Cocaine
Not Metal: Clown who perform for a Sobriety Tour
Metal: Dying face-down in your own heroine-laced vomit, surrounded by unconscious naked women in a trashed hotel room
Not Metal: Dying from auto-erotic asphyxiation while dressed in a Batman costume
REALLY Not Metal: Same as above, but in a Tele-Tubby costume.
Metal: Making out with a chick dressed as a Vampire or Succubus.
Not Metal: Making out with a chick dressed as a Schoolgirl or Cheerleader (again, the Hairspray "Metal" exception comes into play... or if said cheerleader/schoolgirl also happens to be a vampire/succubus)
Metal: Being angst-laden, incompetent, and living with your parents
Not Metal: Being a role model or productive member of society.
Metal: Black leather
Not Metal: Neon Spandex
