When I was 17, my friend mike (aka scorch) got me a deeptht account. We were in his room setting it up, with Dragon Ball Z playing in the background. I was having a hard time thinking up a login name, so I was looking around the room for some inspiration.

My favorite Dragon Ball Z character then came on the screen. "Gohan" I told mike. A few weeks later I found out that gohan was a completely different character and the guy I was thinking about was called Krillin. But I liked the name Gohan better.

And it means rice in japanese.

So I kept it.
