You may be familiar with an arbitrard if you've noticed:
1. those who refuse to wipe their butt-crust off the back of toilet seats
2. when something goes awry, you can bet a gazillion bucks they'll assign blame to everyone but themselves
3. a know-it-all
4. in the midst of an argument, irrational people who refuse to contemplate evidence staring them straight in the eye
5. people who personify Albert Einstein's supposed definition of insanity....they literally rehash the exact same stuff and wonder why nothing's right

Mike: It's the path of arbitrards to always disregard his friend's advice while utilizing his free labor.
