This is about half a year late, but I thought I'd put a smile on your face via the power of poo.

October 10th was Toilet Day! The above poster was made by the school nurse at one of my junior high schools.

This is "hard poo". If you've got hard poo, eat more vegetables!

This is "feels good going out poo". This is "perfect, splendid poo from a healthy body".

This is "kind of soft poo". If you chew your food well it will become nicer poo.

I think this nasty dude is self-explanatory.
