When your superhero plan hits a mathematical roadblock! The purple guy's plan to "balance the universe" by eliminating half of everything crashes into a fundamental mathematical truth: dividing infinity by 2 still gives you infinity. It's like trying to make your student debt smaller by paying half of it, but the interest keeps it infinite anyway. Mathematicians have been chuckling about this property for centuries while the rest of us just discovered it through cosmic villain logic.
This is why you should always consult a mathematician before embarking on universal genocide. Would have saved everyone a lot of trouble!
