1) iPhone 5 - Unless you want to incur the wrath of Steve Jobs, and a 2 hour conversation with him on the right way to hold it, it's best to set your creative talents elsewhere.

2) Milkshake - Why risk having tons of kids come to your house wherein you run out of candy? Sometimes it may be good to have your milkshake bring all the boys to the yard, but not on Halloween.

3) Reindeer - Not because they're necessarily offensive, but it is Halloween after all and not Christmas. Nobody wants to see fireworks on Easter and the same goes with reindeer in our pumpkins.

4) Bowling Ball - Not because it's crude or disgusting, it's just lazy.

5) Swastika - Really anything to do with Hitler and Nazis is a pretty big no-no for any holiday (so yes, no Hitler images for your pumpkins either).

6) Crayons - Sure, they're silly little things used by children, but undoubtedly someone will think you said you carved a Quran and you'll get your house TP'd or egged.

7) Your Social Security Number - You may think you've got your bases covered because you pay for LifeLock but why risk it, especially when their CEO has identity theft issues?
