I woke up one night to my cat batting me in the face over and over again, something he never did. I was sleeping on the couch in the living room and when I put my feet down on the carpet they went squish. My cat liked to sleep in the bathroom sink, and on this night he managed to simultaneously push the drain closed and flip up the faucet lever. The sink had no overflow drain (I have no idea why not) so it just started flooding the whole house. I don't know how long this went on, but most of the first floor carpet was soaked and a bunch of water had gone into the basement through the floorboards and vents.

I was really impressed that Mr. Needy knew something was wrong and that he needed to wake me the fuck up to deal with it.
