(S)he's Right Behind Me, Isn't (S)he?

This has happened to a lot of people. It may well have happened to you. It has certainly happened to me. If you are an innocent here, then take this great mashup by Plot Point Productions as a piece of visual advice: never badmouth someone with your back to the door through which they may enter. It doesn’t have to be a door, either, as you will see.

This is a great collection of those moments when someone says something about someone else and that person is right behind them.  It takes in a number of films: Miss Congeniality, City Slickers and Goldeneye to name but a few. TV shows are also well represented, with Supernatural, Justice League and Crossing Jordan among others. What is that German word again? Ah yes, schadenfreude...
