What do you do with a friend who has five DUI's, and continues to drink? You trick him into thinking he was in a coma for 10 years because of his drinking. Tom Mabe and Jim Clark did just this with their friend, making him believe he was in a car accident when he woke up after passing out from drinking.
This is a great trick, with a good message, but I would have made that news segment just a tad bit more believable. But seriously, don't drink and drive.
