Sean is one of those guys that is able to obtain that perfect balance of "cool" (yes, going by that classic definition of "cool" that I shall not debate right now) and nerdy. He turns the nerd on and off like a faucet. That's kinda what I first noticed when I got to know him, that he was like Kevin Randall. >=D

His diversity is what's cool, though. Like, at 3PM, you could talk to him about cool graphics processing programs like Paint Shop Pro and Photoshop. At 7PM, you can talk about sweet bands like Blink and the Floyd. And at 3AM, a simple "*urinates on you*" will pass for a conversation. Great stuff, man.
