This is the take home clip: "Ghyslain Raza, also known as the "Star Wars Kid", learned this the hard way. In 2002, the somewhat overweight and slightly awkward Canadian adolescent made a video of himself playing with a pretend light sabre and left it lying around at school. When his classmates found the video in 2003, they posted it online as a joke.Raza was so upset he finished the school year from a psychiatric ward. Unfortunately for him, it wasn't just his friends who found the video amusing. According to UK marketing firm The Viral Factory, it became the internet's most downloaded video of 2006."

Be careful who you laugh at.
