Ed Begley Jr. and his put-upon wife, Rachelle, are back for another season of high jinks with their environmentally friendly reality show that chronicles Ed's good-intentioned efforts to go green. The second season opens with a visit to Cheryl Tiegs's Bel Air home, where Ed assesses the former supermodel's Earth IQ. The couple also trade tips and tricks with Larry Hagman, Jackson Browne, Jay Leno, Helen Hunt and "Science Guy" Bill Nye.
