Memory:Doppleganger

Shock! You reel back in horror and dismay as you confront your own body and face where a moment ago was only a pale and indeterminant humanoid form. Your own face leers horribly back at you as you start to wonder just who is who and what is going on. If you're over there, then who is standing here? Exhibit A is a well-groomed adventurer; nothing unusual, they come here by the dozen. Now please turn your attention to Exhibit B which appears to be the exact same adventurer, but if you look carefully, you'll notice...wait a moment, lemme think...humm... o.k., have a careful look at Exhibit A and... damnit, i must of forgotten which is which! And I thought my doppelganger stamping technique finally let you tell the difference. Well, back to the drawing board.
