You feel an odd sensation, and figure the wish is starting to take effect. With a shock, however, you realize the feeling is centered on your abdomen. You have a bad feeling about the wish as you head to the back corner to the restroom and lock yourself in. The feeling becomes stronger, and there is a bulge forming on your abdomen. It grows larger, and you unzip your pants before it bursts through. With a sinking feeling, you realize what must be happening. "When I made the wish, I said 'cow'," you think. "This wasn't what I meant," you say aloud, but of course nothing happens. When the bulge reaches about the size of a basketball, it slows down. You see teats form on the end, and the change stops. "A guy with an udder," you mumble to yourself, while shaking your head. "I just had to word my wish vaguely."
There's only one thought on your mind: get back to the machine and fix this.
