Yup. Son kept talking about how he's going to flush me down the potty and it would drive me nuts "do not say that, it's not nice/not appropriate/etc

Now he's been saying it to little sister, and little sister thinks it's hilarious and they are going to both flush each other down the potty. And somehow it's a little exasperating yet amusing but not obnoxious. I guess the kid just had to find his audience. lol
