I really disagree with this... I've known a number of BRILLIANT people who are complete dicks and feel the need to make sure everybody know they're smart. An intelligent person doesn't necessarily have any tact or social grace.
For those of you that want to enlarge their e-peen. I scored a 151 here and I took it at 430PM.

The test given to me at the medical clinic on base I scored a 176 and that was take at about 0900 about 3 weeks ago. That's out of a possible 200 points on both.
