I picked it because When I was younger, I wanted an email so I could stop using my dads, So my cousin helped me out. My OTHER cousins' emails were The(insert nickname)Myster, so I though, What the heck, Why not? So Since my nickname is Jony (NOT Johny, Johnny, or Jonny because my name is spelled Jonathan. It ISN'T spelled Johnathan, Johnnathan, or Jonnathan.) It was TheJonyMyster. Pretty much ANY TheJonyMyster is me (can't guarantee on sites where you can't post things)
I've stuck with it forever. and ever. and ever. AND EVER.
