As I was folding laundry, I heard the kids in the bathroom arguing with each other: "No, it's MINE." NO IT's MINE!!!" You get the picture.
It was starting escalate and was starting to turn into a screaming match, so I decided to investigate.
What was this big argument about?
Who's turd was it in the toilet.
That's what it was about.
The fight was about who's it was and who was going to get to flush this creation. The end result was that they both put their hands on the handle and flushed together since we never did determine exactly who it belonged to.
