Imagine that you are meeting someone whom you have never seen before, nor has he or she seen you. Since you will be meeting in a busy public place and any number of people with similar physical characteristics (height, weight, hair and eye color) and clothing could be there. Describe yourself so well that the person you are meeting will immeditately recognize you. 25 word maximum.

Why not just wear a sign?

There could be other people wearing signs.

Well, I'd print a random 100 byte text string on mine, which I would then only share with the person I'm meeting.
The chances of someone else having the same string are astronomical, and I'm still in under the 100 word limit, assuming a System/360 architecture.

Ironically, that does more to describe you than anything you could possibly have written about yourself.
