If you want to figure out who the slob is in your office that keeps leaving the microwave full of disgusting, dried up goo, may I suggest the Adopt a Wall method. It works. You see, each person in the office chooses a wall inside the microwave to keep clean. One person for the back wall, one person for each side wall, one for the glass tray at the bottom, one for the inside of the door, and so on. By the end of the week it’ll be easy to figure out just who the disgusting pig is. It’s Debbie.
