(S02E05) "Saving The Environment While Maintaining Profitability." - Greenzo's slogan for NBC's Green Week

I really don't know how I feel about all of these guest stars this season. On the one hand, they've all worked. It was natural to have Jerry Seinfeld on the season opener (even if he was on just to plug that damn movie) because he was an old NBC star. Carrie Fisher worked because she wasn't hyping anything and is a great character actress. And now in this episode we have both David Schwimmer and Al Gore. They were OK too, mostly because the show around them was so strong, but I can really see this show tipping too far over the line with needless celeb cameos. I really hope that doesn't happen.
