I must confess, I'm a little nervous about tomorrow night's "Earth To America" comedy program airing on TBS at 8/7c. I mean, what if it is boring, or worse yet - awkward and you know, dorky? Fortunately my fears are quelled by the high talent making an appearance. Jack Black, Will Ferrell, Tom Hanks, Steve Martin, Martin Short, Robin Williams, Cedric the Entertainer, Ray Romano and Ben Stiller will be on stage as will Al Franken, Christopher Guest, Julia Louis- Dreyfus, Kevin Nealon, Wanda Sykes, Stephen Colbert, Rob Corddry, and, from the puppet world, Triumph the Insult Comic Dog and the cast of "Avenue Q." Who knew they were wacko treehugger types? Hats off to organizer Laurie David for bringing them all together.
