kitchen shower: an added bonus

So here I am, just took a shower, minding my own business while walking downstairs. Suddenly, I hear running water. Strange, I wonder, did I not shut off the kitchen faucet?

I round the corner, and my brain takes a few moments to process what I'm seeing. Water is flowing from the light fixture in the middle of the kitchen ceiling - no, not dripping, we're talking waterfall action here. If my life was a comic strip (which I sometimes suspect it is), you would see multiple "WTF?" clouds popping up over my head. I race downstairs to shut off the water and turn off the power to the light fixture, then go at the pool of water in my kitchen with a mop. With the damage contain, I start pondering over where the water could be coming from - could be the heating system, the drains, or the water supply lines. The possibilities are endless and very exciting, mostly because pipes have a bad habit of hiding behind walls and floors...

My dad came over, and we tried to figure out the source of the leak through the process of deduction, turning on and off multiple faucets with mixed results. Finally, since I was about to start renovating the bathroom, we decided to rip sh#t up, and that's exactly what we did:

After a few hours of removing underlayment, shower surround, and skin from fingers, we found that a crappy connection between two drain pipes corroded to the point of leaking. We should be able to fix it, but my bathroom is probably gonna look like prehistoric for a few days to come.
