This from NBC today:
NBC announced today that Emmy winner and comedy superstar Chevy Chase ("Caddyshack," "Fletch") begins filming this week on NBC's "Law & Order." Chase guest stars as a television celebrity who is pulled over for drunk driving while wearing blood-soaked clothes, and whose religious prejudice comes out after his arrest. The episode titled "In Vino Veritas" is slated to air on Friday, November 3, 10-11 p.m ET/PT.
Obviously, some details will be changed so it isn't exactly about Mel Gibson -- just the way last week's episode wasn't exactly about Britney and K-Fed. (For one thing, ''L&O's'' K-Fed variation was smart.) But you don't have to look very hard to see which headline was ripped for the episode.
