ABCD
Proof

[[A courtroom. A judge sits on a stage at the right. Another man sits, downcast, behind a desk at the left. A man, Zeno, stands centre left holding an arrow.]]
Zeno: My client couldn't have killed anyone with this arrow, and I can *prove* it!
Judge: I'd like to examine your proof, Zeno. You may approach the bench.
Zeno: But never reach it!
