I blue myself
My toliet stopped working this morning. It had not been flushing properly for a few day, requiring a little extra elbow grease to get it to flush properly and today it finally just gave up the ghost. There is, or was, a plastic rod that goes from the flushing lever on the inside of the toliet tank to the stopper that lifts up to let the water flow into the bowl and that is what's broken. It simply got sick of being submereged in water and snapped.
When playing toliet doctor and diagnosing the problem I had my hands submereged in the tank of water, which is blue and bleachy because of the 2,000 Flushes puck that I dropped into the tank about a month ago. Now my hands are blue in colour, just like Tobias [ad].
