For those who may not know, Tom and Ray are mechanics who were the hosts of the Car Talk radio show that aired on NPR from 1987 to 2012 (edited past episodes are still aired online weekly I think). The radio show would take listener calls about their car problems, and Tom and Ray would help them solve these issues. However, that is a very reductive description that does not capture the unique explosive humor, rapport, and varied conversations and observations about the minutiae of everyday life and the human condition.
The HN crowd may enjoy the weekly puzzlers that are presented every week ranging from car puzzles, logic / mathematics puzzles, and historic folkloric puzzles.
