My boss is notorious for hanging up annoying little "motivational" signs in every which corner. One day he even went as far as to tape up a bright yellow sign above the men's room sink that read: "Think!"
The next day my co-workers and I had a good laugh when we went to the men's room. Right below my boss's sign, just above the soap dispenser, someone had posted another sign. It read: "Thoap!"
