Depending on how the prompt is phrased it can result in a response like "it would be inappropriate to throw an octopus at this conference," have the character actually attempt it but usually be foiled during the attempt like "as you take the octopus from your suitcase a security guard stops you with a growl, 'you better not try that kid'," or have it happen but immediately get a stiff response like being kicked out. (It's much harder to get the response "there is no octopus in your suitcase"!)
