What is the best thing to add to someone's "to do" list without their knowledge? AskReddit

I find myself wanting add entries to posted "to do" lists on refrigerators and such when I am visiting friends. What is the funniest, most insightful, cruelest or otherwise noteworthy thing you can think of to add in such a situation?
