The Police Lock

"For a while, I had this thing in my apartment called a police lock. It was actually like a 4' long bar that set into the floor and braced against the door. The idea behind it is once the burglar breaks into your house, this gives him something to beat you with. So they don't waste time looking around for a bust of Beethoven or something. You're done sooner, he's home earlier. It works out best for everybody." - Jerry Seinfeld
