Why is this in spamming and trolling, I don't get it?
The best way to have the most exclusive award is to NEVER give it out. Name it mystery and don't give it to anyone including yourself. Or, if you want a somewhat attainable award, that'd still be a cool award. Just give it guidelines on achieving it, but don't let them be known to anyone other than yourself. Then, if you come across someone who meets these guidelines, hand it out without any notice. Now that I think about it, this would be a sick award. I wish I could change mine to this. Haha. You could also just make the image a question mark.
