Halloween's right around the corner, so what better way to give your company the finger than by dressing up as something blatantly offensive. Here are five costumes guaranteed to kill the holiday cheer faster than a razor blade hidden in a Snickers bar:

1. Hitler at a Barnes and Noble party

Barnes and Noble encourages their employees to dress as a literary figure for Halloween, so what better costume than the author of Mein Kampf? I can't think of a Final Solution more awesome than glaring at a bunch of kids during story hour, can you?

2. Impoverished Asian sweatshop worker at the Nike party

With Nike's motto being "Just Do It," how can you not show up as a lowly sweatshop worker? A bit of caution, though: You may get mistaken for the hired help and might end up carrying h'ors douvres trays around all night. Either that, or someone will shove a pair of unlaced Shox at you and bark, "Get back to the warehouse! No party for you!"

3. Osama bin Laden at the White House party

If you don't mind getting tackled and taser'd right next to the punch bowl, then this is the costume for you. To be honest, however, I don't think anyone at the White House will come remotely close to recognizing the costume. You probably have a better chance at getting detained if you go dressed as a mummy than bin Laden, simply because Bush saw the movie and thought it was scary.

4. Lab Monkey at a PETA party

Looking to crash PETA's self-righteous, meat-free, cruelty-free, and fun-free Halloween party? Then go as a loveable lab monkey! Really sell the costume with protruding tubes and exposed brain matter, then put on your happy face as if to say, "Yes, I'm experimented on! I could be the catalyst that leads to a cure for cancer! It sure feels great!"

5. Bottle of Jack Daniels at an AA party

An AA party is bound to be a real snoozer, so why not spice things up by dressing as each party goer's greatest vice? Halloween never tasted so good or shameless. Some advice: I wouldn't recommend wearing this costume around Tara Reid out of fear that she may devour you.
