Today's Halloween costume-related warning comes from My Parents Loved Halloween, a new Tumblr that features this spectacular Mr. T costume fail from 1984, the year of the Macintosh computer, "Ghostbusters" and "The A-Team" costumes.

This poor little kid has no idea how offensive he is, all dressed up in blackface. He's also lucky the police didn't shoot him for "possessing a gun while looking black." (Racial profiling was a big problem even then.)

Couldn't they have just given the kid a mohawk (even a fake one) and called it a night? The T-shirt lets us know what he's supposed to be, so there's no need to get all Al Jolson on this poor kid.
