Who's been sleeping in my bed? A naked, strange man
You come home after a night out with your girlfriend. She drops you off late, around 5 a.m. You walk in your home and find water dripping down from the kitchen ceiling. You go upstairs and see the bathroom sink is backed up, water running and overflowing onto the floor and through the ceiling downstairs. You turn off the faucet, go to your bedroom and find a strange man sleeping there -- covered with blankets but naked.
