For Kermit the Frog, being green is a part of life—but it's not a look he recommends for Peter's human listeners. "In terms of the actual, literal color green … if any of you actually notice yourselves turning green, you probably should see a physician!" Kermit says.

Having made that distinction clear, Kermit shares with Peter a few ways folks really can go green:

• Turn off the lights when you leave a room.
• Consider driving a hybrid vehicle.
• Keep pigs away from your credit card. "Okay, that last one won't save the world, but it's good advice all around," Kermit jokes.
