Well, there are two reasons. The first is easy, I share the same first name as Steve Yzerman, the starting center for the Detroit Red Wings. (If you're just putting that all together now, congratz, treat yourself to some Snausages.) But the main reason came from my hobby in college, smoking lots of pot. Pot really bloodshoots my eyes and they were always red. It's a dead giveaway that I've been smoking, and Visine don't help. Once I smoked so much, my iris sprung a leak and leaked pigment into the rest of my eye. There's still a spot to this day. Fortunately I don't have that problem anymore, because I am an upstanding, law-abiding citizen with no perverted hang-ups of any kind or bench warrants. Now come pick me up, and, uh, bring some bail money. And a leash. I've been naughty.
Anyway my friends started calling me Izerman, Ize, even Ize-Fu when I had a goatee. (As in Fu Manchu. Oh you knew that? Good boy, Snausage Time.) The first time I named one of my characters on Dark Castle accordingly, it was Ize, my thief when I joined Bandaleros. That was my first attempt at evility, and it was alot of fun. People couldn't pronounce it right, though, so I had to put "pronounced Eyes" in my name. They couldn't rationalize nor harmonize the pronounciation. Anyway, there you have it. Doubtless you'll catch up on all that sleep you've been missing.
