This should be an easy call. Why? Because, all the players fold, one player goes all in and I have AA, The best hand you can get preflop. I would call and go all in.
I'd call and blush as everyone hears a big thump under the table above my lap...... Probably get beat 1 out of every 5 times anyway but you can't fold with that chance to triple up sitting in your hands. If the flop came out before the all in it would be a much more situation-specific answer.
