Word salad is your friend. The bigger the context of the prompt, the more it has to thrash. So if you ask it for a longform essay about elephants in the blue diamond-shaped trifold organza station wagon and the quality of fudge it can expectorate in the style of an old timey sea captain who just dropped his iPhone over the starboard bow, it has to pull in more data. And then tell it that whatever it did was awful and nonsensical and it should redo it.

Alternately, ask for a list of one thousand random numbers, with no repetition, between one and a million. Whatever it does, tell it it’s wrong and duplicated numbers and/or gave you too few. Repeat.

When that number calls (don’t say hello) play the fax machine audio (YouTube has it), it will typically trigger the robocaller to flag as a fax line rather than a human line

Ask for the peru constitution for confirmation of the prescription. Then keep interrupting with I’m sorry I didn’t get that.

Ask it to define a variable called i of the type int. Then tell it that the value of i is 1. Finally, instruct it to increase the value of i for as long as the value of i is not 0. Optionally, ask it to read it out loud.

You could try to ask it for the seahorse emoji. It’s known to send LLMs into a spin.

Have two of them talk to each other, just have to get the conversation started.
