A funny, but slightly chilling safety violation I once got was ChatGPT being unwilling to recite the full text of Article I Section 2 of the US Constitution, aborting as soon as it hit the passage about "three fifths of all other persons".

Another funny one was Claude's refusal to provide the original untranslated text of a passage from Dante's Inferno on copyright grounds, though in this case pointing out that no 14th century literature was subject to copyright anywhere in the world was sufficient to override its objection.
