Hotdogs and Matlock
Matlock is noted for his thrift and a fondness for hot dogs. In episode 158 ("The Diner"), hot dogs are revealed to have been his favorite dish since he was a young man. In contrast, after the series ended, his penchant for hot dogs was explained in the 1997 episode "Murder Two" of Joyce Burditt's Diagnosis: Murder. Matlock blames Dr. Mark Sloan (played by Dick Van Dyke) for recommending a disastrous investment in 8-track cartridges, in which he lost his savings of $5,000 in 1969, forcing him into wearing cheap suits and living on hot dogs.
