On April 22, 1990, the Muppets marked Earth Day with a two-hour special jam-packed with guest stars. The list is absurdly long, but I'll give you a taste -- the cast included Neil Patrick Harris, Carl Sagan, Dustin Hoffman, Tone-Loc, Will Smith, Dan Akroyd, Chevy Chase, Downtown Julie Brown, Candice Bergen, Danny DeVito, Rhea Perlman, Morgan Freeman, Queen Latifah, Jack Lemmon, Edward James Olmos, Christopher Lloyd, Rick Moranis, Martin Short, Meryl Streep, Alex Trebek, Robin Williams, and...wait for it...the casts of The Cosby Show, Cheers, Married With Children, and Golden Girls. Plus a bunch more. You get the point, though, right? Basically everybody was in this thing. Because the guest list was so long, there's relatively little Muppet material (though that material was directed by Jim Henson), but I'll take any Muppet-related Earth Day video I can get. And, shocker, the whole thing is on YouTube.
So, twenty-three years later, settle in and grab some popcorn, and enjoy this nugget from the past. Keep in mind that Jim Henson died on May 16, 1990, so this was among the last major works he lived to see on the air. Henson was a devoted environmentalist, so I can only assume that 23 years ago today, he was proud.
Robin Williams testifies.
Doogie Howser, M.D. tries to save Mother Earth while Murphy Brown reports, then we get into the Jeopardy! material.
Carl Sagan drops knowledge until Danny DeVito changes the channel in favor of Dennis Miller's Weekend Update segment on SNL. Around 3:50 into this segment is a sketch written by Henson featuring Kermit and fellow swamp animals. And then Dustin Hoffman argues with Robin Williams. Oh yeah...and then E.T. shows up. What?!
Let the 1990 TV-friendly rap number begin!
Michael Keaton apologizes for his polluting ways, then we eventually get into some Married With Children tomfoolery.
Meryl Streep! Kevin Costner with a ponytail! The cast of Cheers!
Murphy Brown wraps up her reporting as everybody realizes there's something they can do to help...and then Barbra Streisand performs, before a rapid-fire set of tips from celebrities including Morgan Freeman.
As a final treat, here are a series of 1991 spots promoting Earth Day (for the National Wildlife Federation) featuring Kermit and various other muppets working for Frog Frog & Frog Advertising, trying to develop a catchy slogan for Earth Day.
And these are a bit earlier (late 1980s):
