Berger and Wyse feed their cat, ala Physics Forums
Not really, because now we know there's nothing in the can.
Edit: unless I'm missing something here
I guess: until you open the can it has both food|no food, (or maybe live food|dead food). However, the cartoonist missed the point. Or did not have poison and a Geiger counter to put in the can.... I don't think poison kills cat food, either. Oh well, I thought it was interesting. If "not even wrong".
