Want to be a real ass for Halloween? Pick up this full face donkey mask at Lynch's. At just 8 bucks, it's a real steal, although you can probably make yourself look like a jackass for free. This mask comes replete with an elastic band in the back, just like on the ones you used to wear as a kid. Pair it with a gray sweatsuit, and you've got yourself a costume that will double as pajamas. Or perhaps check out The Godfather for other pony-themed costume ideas.
