Something that makes me go "hmmmmm!?!" re: Gore's 30 Rock appearance

[Mabus]

Episode guides for "30 Rock" list an episode called "Greenzo" and they have the air day as Nov. 1. Here's an example:

Season 2

22. 2- 1 4 Oct 07 Seinfeld Vision
23. 2- 2 11 Oct 07 Jack Gets in the Game
24. 2- 3 18 Oct 07 The Collection
25. 2- 4 25 Oct 07 Rosemary's Baby
26. 2- 5 1 Nov 07 Greenzo
27. 2- 6 8 Nov 07 Cougars

but, NBC's Green Week doesn't start until Nov. 4 as announced back in July. Their July press release was called "'GREEN IS UNIVERSAL' – NBC UNIVERSAL COMMITS TO WEEKLONG ENVIRONMENTALLY-BASED PROGRAMMING INITIATIVE, NOV. 4 - 10"

So why is the episode "Greenzo" with David Schwimmer as an unemployed actor who finds work as an environmental mascot for the studio (and presumably the episode with Gore) on before NBC's official Green Week? Of course, Gore could appear on the following week's episode "Cougars" but, frankly, "Greenzo" sounds more like an environmentally themed episode than one called "Cougars". Not to mention that Schwimmer's character is an environmental mascot. http://www.tv.com/30-rock/show/58326/season-2-more-guest-stars-less-tgs-andamp-silly-stuff/topic/76681-858619/msgs.html

Can I get another "hmmmmmmm?"
