This is pretty straightforward. Just give the person above a rule they must follow permanently. You may also request a topic, but you don't have to.
RESPECT LIMITS, especially here!

Example:
Person A: Start here.
Person B: Edge 5 times before every meal.
Person C: Give yourself a wedgie every night before bed.

I'll start. My topic is edging.
