flip an image on attach movieclip?

I'm attaching a movieclip to the stage and then setting certain variables to create a rondom feel. I want flash to randomly select NORMAL or MIRRORED. The effect is just a horizontal flip of the original movieclip. I know this is easy for someone, please help.

that would mean altering _xscale:
_xscale=-100;

assuming you know about the random() function.
