Here is the custom report of your personality than led our team of geeks to conclude (with confidence) that you are a resourceful and sly man:

" The subject shows an astounding level of intelligence, and his sense of observation is one of his best qualities. Considering this, he shows a lot of potential, but that's only part of the equation.

Also, as much as we hate violence, an occasional mauling is one way to solve day-to-day problems like unpleasant coworkers or pesky door-to-door salesmen. He just isn't tough enough, sir, and avoids any situation that involves violence.

Finally, the subject displayed a pathetic and useless (seriously bad) sense of humor, a nearly satanic lack of morality, and a complete lack of self-confidence. The balance of these three traits is important; high levels of confidence, medium levels of morality, and a good level of humor make for the strongest individuals. "

Woohoo! I'm a resourceful and sly man.
