T-Rex: Literally hours of work have paid off, and I have come up with my greatest invention yet... a DUPLICATOR RAY!

T-Rex: (Duplicator rays let you make perfect copies of anything!)

Dromiceiomimus: Really? So if I have, say, a papier-mâché piñata dog filled with tasty candies, your duplicator ray will make a PERFECT duplicate?
T-Rex: Yep! The duplicate is identical in every regard. The ray examines the object at the quantum AND subquantum levels and thanks to the twin fists of Actual Science and Heisenberg Compensators, makes a perfect copy, indistinguishable from the original!

Utahraptor: I call baloney, T-Rex!
T-Rex: Aha! On account of how it violates conservation of energy laws?

Utahraptor: Nope, on account of how it's truly impossible to have a perfect copy of anything! Philosophically: if I paint a picture and you duplicate it, I'll grant that they can be identical in every way BUT ONE: mine is the original. That's a property that doesn't have a physical realization, so you can't ever duplicate it!

T-Rex: Okay YEAH it's not original, but it's an OTHERWISE PERFECT DUPLICATE. I can destroy economies based on scarcity and generate clean drinking water for everyone! I can even DUPLICATE DUDES! I can't believe you're not more excited.
T-Rex: I CAN DUPLICATE BRENT SPINER
