Get your shit together

This has been an amazing night in the world of shared toilets.

At first I discovered this:

Having only my phone with me, I took a picture just in case someone were to clean it up by the time I got my camera. And the shitty (pun intended) quality calls for a caption: YES, that is shit on the floor in front of the toilet.

Then; when I got back from getting my camera:

Someone had already stepped in it! Oh, the exitement!

On closer inspection I realised the runaway poo had left a trail

How is it humanly possible to take a shit, aim at the toilet (grasping at straws here people, but we have to give the poor girl som credit, she DID at least aim into the toilet?!) And then manage to "lose" a small piece along the outside, that mind you, goes in UNDER the seat?
(It might not be entirely visible in the picture, but the marks almost at the top of the bowl is the trail)

I'm puzzled
