Someone else posted this before, can't seem to find it now but I kept the text:

"Explaining well known concepts - especially if you ask it to invent analogies or mnemonics. Helping come up with names for things.

Puns, surprisingly.

Finding and fixing bugs in code.

Generating test data, and examples generally.

Telling stories.

Games - so many fun games you can play with it."
