After 25 years as the host of "Nightline," Ted Koppel has chosen to go out in an unconventional fashion.
Rather than have his final "Nightline" broadcast (10:35 p.m. Tuesday, WLS-Ch. 7) feature a series of clips highlighting his most memorable interviews and the news program's most famous moments -- a stroll down memory lane that the retiring newsman deserves -- Koppel gives his last show to a man who has been dead for 10 years.
