What is a Warrior to Wear?

Warrior Dash 2010 is 6 days away. OMG, WTF and IDKwhatIwasthinking and every other acronym under the sun is going through my head as time draws near.
For those of you who haven't heard of it, Warrior Dash is a 3 1/2 mile marine-style obstacle course and race. You get a beer and a viking helmet for crossing the finish line. The only guarantee you have in this race is that you will be very dirty by the end. Cargo-net climbing, walking the plank, mud slide, climbing beneath barbed wire-you name it. I am so flipping excited I can't stand it.
But how to train for this? I don't exactly have any swamps or millitary training facilities handy, so I am just running my tush off--or trying to.
I did 3.5 ml today and it finally felt 'good' (as in no stopping, no cramping and minimal swearing). Last week in order to try to push myself a little more I attempted to insert my own local obtacles in my run, but I'm just not sure that it will suffice.

I am warrior-ing with Michela Palmer, my calm and beautiful, PhD-earning, soccer mom with doting husband, friend. (Thank God she is so sweet because being friends with her might almost be too much to bear, j/k Mic!)
We are both in dire need of a little more fun-crazy, versus crazy-busy in our lives and so...
Some warriors come in costume or warrior gear and we need to decide if we are going to do this.
I am drawing a blank, but I would love to hear any ideas from you. Funny T-shirt logos, color schemes or outfit suggestions would be greatly appreciated. Just remember, we are going to have to move--and slide, climb, run and try not to cough up a lung afterwards--in these getups.
