Last night the best and the brightest comedians in the world convened at Caesar's Palace in Las Vegas for “Earth To America!” – a two-hour TV special that aired on TBS. It managed to make America laugh about one of the least funny issues on the planet: global warming. The show’s runaway success was not too surprising given the all-star lineup of comedians, including Will Ferrell, Jack Black, Tom Hanks, Steve Martin, Ben Stiller, and Julia Louis-Dreyfus.
