The Skeleton. Classic for sure. Makes me uncomfortable if I think about it? Yes, very. This costume is at its best when it's 2 sizes too small on a tall guy. You want sleeves that are too short, pants expecting a flood and a pronounced wedgie. That's where this costume really shines. Am I right?

The Monkey. Now I'm thinking that most of the costumes I'm posting would be funnier on a tall guy with a wedgie. But the original reason this costume made the list is the banana. Why add insult to injury? Aren't we getting away with enough here?

The Princess. I'm sooo sick of the princess thing. It's the future, people!

Chewbacca. I know, I posted this one as a suggestion, and I do love it. But I think it's hilarious and that makes me feel a little guilty. Which makes me feel uncomfortable.
