A texting app I had would suggest replies to many of my texts as a shortcut button above the keyboard. So I texted myself a generic "starter" text from another phone and just went back and forth only using the suggested responses.
Back before caller-id a funny prank was to call two numbers at the same time and conference them in. And then listen on the speaker phone. (and record it of course)

Will Godwin's law[1] apply to ChatGPT bots arguing against eachother?
