整理整頓
sei.ri.sei.ton

Literally: organize – logic – organize – immediately

Alternately: Keeping things in order. Tidiness. Not being rough or sloppy in your work. A phrase often seen on posters in classrooms, offices, and construction sites; often cited as part of proper safety precautions.

Note: Bear in mind that in Japanese, ton is pronounced like “tone”; it doesn’t rhyme with “bun” like the American-English word “ton.”

The joke is that the character 豚 (buta, “pig”) can also be pronounced ton. Image from a T-shirt design found on this website.
