You can't believe the image reflected before you. You see yourself, but there is a dark and full beard on your face. Your hand races up to your cheek, but all you find is your normal smooth skin.
"Whoa," you say to yourself, "This is so cool, it must be some kind of high-tech fun-house mirror."
You take a closer look at your reflection and see that, behind the beard, you look older. Your face is that of a rugged, middle-aged man. So realistic is the effect that you feel your face again to confirm that you are still clean-shaven and youthful. "I wonder if this thing has any other tricks?" you wonder aloud.
As if hearing your question, the mirror's image shifts, your reflection grows larger, burlier, its clothes changing to a partially open flannel shirt, jeans, and leather boots. You examine the altered image and see a thick mat of hair poking though the top of the shirt, and the crotch of your reflection looks a bit more prodigious.
You start posing, enjoying how the brute in the mirror follows your actions perfectly. "I need to get me one of these things," you say to yourself as you scratch your beard.
Wait...
Beard?
Your hand races back to your face again, but this time a thick beard meets your hand, which has become larger and calloused. You turn away from the mirror and look down at yourself. You're now wearing a flannel shirt, dark hair adorning your chest.
You whirl back to the mirror, the hirsute man in the reflection no longer an illusion. "What the hell?!" you yell out in a deep, booming voice. You slam one of your meaty fists on the glass, hoping that breaking the glass will return you to normal. Instead, your image changes again, your body staying the same, bu your clothing switches. You see yourself dressed only in leather shorts, exposing your new, hairy torso and round gut. You pound again and find yourself nearly nude, wearing only a tattered jockstrap, barely covering your larger loins.
You pound one last time, and you find yourself wearing all leather; pants, boots, jacket, and cap. The mirror shudders slightly, then a strange wave of force knocks you away from the mirror. You're knocked to the ground, but you get back up in time to see the door over the glass slam shut.
Running over to the door, you find it locked tight, leaving you stuck in the body of a hairy behemoth dressed like a biker.
