Japanese Children's book Everyone Poops.
Yes.
Hey, some people need to be told. If our current president had been given this as child, he wouldn't keep making that squinty face all the time, we're sure of it. We see you George, not making any long strides, keeping the butt clenched-- you got to let go, man.

If the cute NAMBLA-esque images of everybody poops end too quickly for you, there's a whole tiny industry based on the the book's success.
