There was a knock on the door. With a sigh, Professor Schrödinger moved to answer it, adjusting his lab-coat as he did so. He opened it to find two men with stern expressions standing on the doorstep.
"Erwin Schrödinger?" The first asked. After Schrödinger nodded, the man continued.
"Can we come in please? We need to talk to you."
"What is it?" Schrödinger replied. "I'm in the middle of an experiment."
"Yes, that's rather the problem you see. We're here because some of your neighbours reported their cats had gone missing. Apparently, you were seen with several of the cats in your back yard."
"Yes. Yes, of course. Please come in, this is a simple misunderstanding," Erwin replied. He lead the two men inside, taking them into his Laboratory. "You see, I put the cats in here"
The group paused, and the two men looked at the steel chamber in front of them.
"Sir, we take mistreating animals very seriously. Is the cat all right in there?"
"Oh, yes, of course. Well - partly. You see, I've placed the cat in the chamber with a flask of poison..."
Here, he was interrupted, and the men shoved him aside as the rushed to open the chamber.
"Wait," He cried. "While the chamber is sealed, the cat is both alive and dead! You see, there's no harm done to it."
"Alive and dead?" Queried the second man. "Don't be so stupid. You're under arrest."
