Your water system has gone plumb crazy.

In my case, my sink is a geological phenomenon. Seriously. For the last several years, there have been occasional times when I have heard odd, high pitched, pinging sounds that I haven't been able to track down. Eventually, I end up in the bathroom and find shards of enamel scattered around the sink. The force of the explosions are fairly impressive, as shards have been thrown a couple feet, at least. This went on for a year or two, then went dormant for well over a year, until last week, when a series of minor eruptions scattered shards all over the sink, though none of the shards made it very far.

So you may have erotic appliances with more tension than an afternoon soap opera, but I have an exploding sink. It's all good fun.
