I think if Misha came in (which, technically COULD HAPPEN—in my head, when he is not acting or tweeting or being The Puppet Master, the dude reads) I would actually die. Or momentarily cease to function. It would be very embarrassing.

Alternately, I would somehow manage to find it within myself to be cool as a cucumber (which is my usual thing) for the space of time in which he was physically in the store. THEN, once he left, I would die, etc.

Of course, I have not spent any time considering this possibility AT ALL.
