Markup voodoo is still better than plumbing
Kudos to danguyf for keeping me from developing a knot on my forehead from repetitive head-banging on my desktop.

Is there some awkward planetary alignment going on? Because my brain pipes were seriously clogged with junk info before the webgoblin introduced me to Firebug. Woah. Lightbulb moment!

There is also a serious clog in the traditional plumbing, which just sent a plumber with 11 years experience fleeing from the house with a promise to send someone else to tackle it. Hm. The kitchen sink has long housed some vocal poltergeist who wailed and moaned when a tap was turned. Now water rises up out of the drain and falls away like the tide. No one seems sure where it's coming from. All other plumbing in the house is happy and healthy. If I were a real-estate agent, I'd call this an "indoor water feature" meant to instill serenity by watching the water gently flow in and out.

I'm not entirely convinced that this wasn't ancient Indian burial grounds before it was farmland (and now sprawl).
