Guilty pleasures and similar personalities

Listening to a disembodied voice pontificate on Tiger Wood's place in the pantheon of golf heroes is probably not what most people would choose to listen to on a drive to work.   The essentially ridiculous nature of the discussion on the PGA channel on XM radio embarrassed me enough to change the channel to another staple on my radio, MSNBC, where Joe Scarborough was holding forth on Marco Rubio and his chances at the Republican nomination for president.  The similarity was striking and I began to wonder what it says about the frontal cortex of someone who listens to such drivel on a regular basis.
