[cassowary]

How can someone seriously propose I put a copyrighted symbol in my text to let them know it's sarcastic? [rhetorical question device] I'll bet the world will be a better place if they profit off every sarcastic sentence someone writes. [sarcastic sentence device] If you're too dumb to work out what's sarcastic, why should you benefit from my help? [friendly period]

(nb. There's a missing "sarcastic sentence device", but I don't know where to put it, when it applies to a piece of punctuation.)
