Tom Magliozzi of NPR's 'Car Talk' Dead at 77

A sad day.

Tom Magliozzi, one of public radio's most popular personalities, died on Monday of complications from Alzheimer's disease. He was 77 years old.

Tom and his brother, Ray, became famous as "Click and Clack the Tappet Brothers" on the weekly NPR show Car Talk. They bantered, told jokes, laughed and sometimes even gave pretty good advice to listeners who called in with their car troubles.

If there was one thing that defined Tom Magliozzi, it was his laugh. It was loud, it was constant, it was infectious.
