Returned from a weeklong trip and surprised that nobody posted this (or at least I did not find it with a cursory search).

The problem was someone had flushed a latex glove into the lavatory and plugged it up. This was a flight from Shannon to Newark. I heard Jay Leno joking that the plane stank all the way across the pond, but when it landed, the passengers thought EWR stunk even more and wanted to get back on.

I fly CAL a lot now and this better not happen on my flights, but I understand that crap happens sometimes. Just not to this extent.
