The kitchen ceiling... or, at least, that section of it that's directly under the drain for the upstairs bath. The day after we bought the farm my wife took a bath upstairs, and seconds after she pulled the plug we discovered that the bath had no plumbing underneath it, and so drained directly into the kitchen!
The upstairs toilet had the same problem, but with the dining room. Luckily we found this out when testing it to see if it flushed without having used it!
