A soldier at the Pentagon got out of the shower and realized that his clothes were missing. While searching around for them, he accidentally locked himself out of the locker room, and he found himself completely naked in the halls of the world's most powerful military organization HQ. But, luckily, no one was around to see him.
So, he ran as fast as he could to the elevator. When it arrived, it was empty. He breathed a sigh of relief and got in. When the doors opened on his floor, there was no one waiting outside. "This must be my lucky day," he said to himself. He was now only a few yards from his office.
Suddenly, he heard footsteps from around the corner. He heard the General's voice. There was no way he would make it to his door in time, so he ducked into the closest closet office available, and found himself in the laboratory for Research and Development. The Head Scientist looked up from one of her experiments with puzzled interest.
The soldier thought quickly, stood up straight and saluted.
"I am here to report the partial success of the Personal Invisibility Device," he said.
"I see," the Head Scientist said. "But the Shrink Ray seems to be working perfectly."
