Bill and Kevin are joined onstage by the great Paul F. Tompkins, and together they host and riff an amazing set of bizarre short films. The shorts cover every subject under the sun (y’know, because “Day”), from workplace safety to childhood safety to sentient talking pillow safety. And that’s not all - we’ve got more guests, riffing teams and legends galore! John Hodgman, Frank Conniff & Trace Beaulieu, Cole Stratton & Janet Varney, and Bridget Nelson with Sean Thomason, RiffTrax Senior Writer, making his live riffing debut.

Join Mike, Kevin and Bill, along with guests Bridget Nelson, Mary Jo Pehl, the Mads from MST3K Trace Beaulieu and Frank Conniff, and special guest Paul F. Tompkins and relive this amazing summer-themed night of riffing and comedy!

What do ice-skating reindeer, pipe-smoking santas and a parade of aquatic champions have in common? You’ll see them all in the RiffTrax Live: Christmas Shorts-Stravaganza, now available as Download to Stream, DVD and Blu-ray! The stars of Mystery Science Theater 3000® have a sackfull of delightful and demented shorts to riff live onstage. Some of the forgotten gems of Christmases past prove to be the perfect targets for the rapid-fire riffs of Mike Nelson, Kevin Murphy and Bill Corbett. And if that wasn’t enough, they’re even joined by comedy legend “Weird Al" Yankovic for a musical short about the wonders of pork! It’s funnier than Ernest Saves Christmas and far less creepy than The Polar Express! Join Mike, Kevin, Bill and Al for a festive night of hilarious holiday comedy that is destined to become traditional Christmas viewing.

Mike, Kevin and Bill were joined on stage by their MST3K colleagues at the State Theatre in Minneapolis to bring it back to their roots in an MST3K cast reunion the likes of which have never been seen before! Joining the guys are their old cohorts Frank Conniff (TV's Frank), Trace Beaulieu (Crow, Dr. Forrestor), Mary Jo Pehl (Pearl Forrester), Bridget Nelson (Nuveena, Mr. B), as well as Mystery Science Theater 3000 creator Joel Hodgson, AND the host of the revived MST, Jonah Ray, for a hilarious night of riffing for RiffTrax's 20th Live event. Taking turns in various permutations to riff on a slew of old-timey shorts, the show culminates in a Super Riff-A-Palooza finale with all nine riffers on stage at once!

Deep in the Mexican jungle, a legendary creature lurks in a radioactive swamp. Is it a man? Is it an octopus? No, it’s OCTAMAN! Okay, it’s a man in an octopus suit, but he’s really angry and decides to go on a light killing spree.
