Videology

This is one of my favorite bits that David Letterman has done.  I saw it when it was done on air, many years ago, but figured that was it.  I tried to track it down online, never having any great expectation of finding it -- for starters, I wasn't even quite sure how to search for it -- but never diminish the miracle of search and YouTube!

A viewer sent a letter into Dave, making a quip about how he needs better shoes.  And Letterman decided to respond to her...in person.
