Late Show with David Letterman

Snoop Dogg, Charlie Hill, OK Go

In honor of the show's 13th anniversary, an intern accidentally walks onstage to ask Dave to sign his own greeting card; live from Tracy, California, Ron Patrick drives around in a silver 2000 Volkwagen Bug with a 1,450-horsepower jet engine; Dave tries to interpret Snoop Dogg's "dizzle"-speak; OK Go performed "Here It Goes Again."
