File under things you don't want to happen: Here's a video of a waitress dropping an entire tray of plates on actor Joe Pantoliano (The Sopranos, The Matrix). From the video's description: "Joe Pantoliano... was shooting a scene in a restaurant. The cast was waiting for the film crew to do something off-camera when a waitress walked past the table and spilled a huge tray of food on the actors." It doesn't really look staged, but anything's possible. If it wasn't, that waitress totally got fired.
