so how did you come up with your name?

I am interested to hear how everyone came up with their HotCopper name. Should be interesting and hopefully a tad humorous as well!

My name is not so interesting or funny unfortunately. JAK is my initials and 4 is my favourite number. Why three 4's? I honestly don't know! Maybe it looks better than JAK4 or JAK4444?

I look forward with interest to reading any replies...
