Yes, it's official — Mystery Science Theater 3000 and Rifftax's Mike Nelson, Kevin Murphy and Bill Corbett are returning to TV to make fun of some of the National Geopgraphic channel's programming in Total Riff-Off. And we're proud to debut this first-ever clip!

There will be three hour-long Rifftrax specials, beginning at 8:00 pm EST on April 1st:

• Killer Shrimp n' Friends

• Demon Bat

• Guy and a Goose

And no, this is not a joke, as hopefully the clip above proves. Here's the official press release from Rifftrax:

Yes, that date is April Fool's, but there's no joke here. Well, there will be jokes. Lots of jokes. Jokes told by us, on television. But the fact that there WILL be jokes isn't a joke, you see... Look, we'll start over.

We are incredibly excited to announce that RiffTrax will take over the National Geographic Channel for a special night of riffs, badass dino birds, rage-filled shrimp, demon bats, and more!

The good folks at National Geographic have taught the world about animals, science, and fascinating cultures for years. Now, in their infinite wisdom, they've seen fit to have RiffTrax riffmasters Michael J. Nelson, Bill Corbett, and Kevin Murphy take on some of their wildest, strangest discoveries. This will be the guys' first time riffing on television since Mystery Science Theater 3000, and trust us, you do NOT want to miss it. Think of them as the kids in the back of high school science class cracking wise, except funnier, and with better skin.

So flap your wings, flex your dorsal fin, or just move your regular old boring human feet, but do whatever you have to do to get yourself in front of a TV for the rapid-fire hilarity of TOTAL RIFF OFF on National Geographic!

My whole community is excited!
