Snoop Dogg stopped by the Late Show with David Letterman last night to perform his new Yazoo-sampling single "Boom." Surrounded by dancing girls in tight shiny red pants, Snoop is cool and calm as he spits a typically dense but laid back set of verses. The audience, on the other hand, was totally losing it. When was the last time you saw an entire audience at a late night show clapping and dancing in their seats?
