I'd like a clone. Mostly because I don't like other people. Oh, is this clone exactly the same as me, personality, thought patterns, habits and all at the time of creation? Then ESPECIALLY a clone. So long have I searched for someone to help me absolutely perfectly. Who thought the same as me. Essentially, an extra pair of hands with which to do work. Of course, it'd be more than a tool. Of course I'd be nice to it. That's just the kind of person I am.
Actually, I'd rather have my Y chromosome removed so that my clone is a girl. Not for sex or anything... although that raises some interesting questions. Nope, I'm just curious to see what I'd be like as a girl.
