If you ever used Linux (or a Unix like OS), you probably know that the command rm * erases EVERYTHING. rm -Rf * is even worse. Now think of the damage it can cause in the folder of production files from a movie like... Toy Story 2!?!
This is one of the curious stories from Pixar, released as extras on the Blu-Ray editions of Toy Story and Toy Story 2. Some of these videos are online at slashfilm. Have fun! :)
