Take 5: Green day

Sunday is Earth Day, which makes us think, of course, of all things green, like these five TV characters:

1. RACHEL GREEN -- Jennifer Aniston's "Friends" character, a waitress-turned fashion designer.

2. MR. GREEN JEANS -- Captain Kangaroo's sidekick.

3. GREENZO -- David Schwimmer's bizarre guest superhero on "30 Rock."

4. JEFF GREENE -- Larry David's clueless agent, played by Jeff Garlin on "Curb Your Enthusiasm."

5. DR. MARK GREENE -- Doomed doctor, played by Anthony Edwards on "ER."
