Tom Mabe is a comedian who pulls great public pranks, such as tormenting a telemarketer and being the world's worst babysitter.
But he's a good friend who practices tough love. Mr. Mabe has an alcoholic friend. This friend has had 5 arrests for driving under the influence of alcohol. Mr. Mabe and his colleague Jim Clark staged an intervention in the form of a prank.
After the drunk driver passed out, they moved him into a fake hospital room and convinced him that he had been in a coma for 10 years.
The funniest bit is the news update that the patient sees when he turns on the television.
