Wednesday's Late Night Round-Up: Joe Biden's Hair, Eliot Spitzer's Hookers, And Colbert's Earth Day Hate (VIDEO)

Yesterday was Earth Day and all the late night hosts celebrated in their own special ways. Jay Leno used the occasion to mock Joe Biden, Jimmy Kimmel mocked President Obama, and David Letterman mocked Eliot Spitzer. Ok, fine, they all celebrated in exactly the same way. Except for Stephen Colbert.

Colbert has long hated Earth Day, but until it infiltrated his favorite day-time game show, he wasn't at war with it. The "Price Is Right" went green yesterday and the Comedy Central frontman was not happy, my friends. He guessed all the eco-friendly prizes were one dollar.
