If You Never Understoond Why People Love Dave Letterman, You Have To See This Bit

David Letterman has been a pioneer of late night television and has reshaped what it means to be a late night host. He's brought so much ingenuity to his comedic show since he began doing late night in 1982, and there will be a great gap left now that he's retired. 

And of all the ingenious bits, brilliant sketches and just outrageous things done on his show, possibly the all-time greatest is when he pretended to be a worker at Taco Bell.
