* HeyItsThatVoice: Almost by definition. Don't fret if it takes you a while to hear Kevin Murphy as himself and ''not'' picture a red gumball-machine shaped robot.
** Admittedly, many fans ''try'' to pretend Kevin is a red gumball-machined robot and Bill is a golden beaked robot.
*** It mostly works fine that way, except that it can be disorienting when one of them references something in real life like his family, and you have to remind yourself that they aren't robots on a spaceship anymore.
* MissingEpisode: The guys couldn't get the rights to release their live action riff of ''Film/{{StarshipTroopers}}'' on DVD, necessitating a separate audio recording.
** The DVD release of their ''ManosTheHandsOfFate'' live show removed all references to ''Manos 2: The Search for Valley Lodge''.
* OfficialFanSubmittedContent: The jokes for the ''Film/BatmanAndRobin'' trax.
* OneOfUs: The commentaries feature frequent references to nerdy or geeky activities/interests, unsurprising considering we're their target audience. In the ''Film/HarryPotter'' Rifftrax, several jokes were made referencing things that were either only in the books, or hadn't been introduced yet in the films (like a joke involving Horcruxes before the ''Half-Blood Prince'' film had been released). In the ''Film/LordOfTheRings'' rifftrax, the guys gushed about Middle Earth and its rich history, like Mike giving a detailed explanation of the meaning behind Aragorn's war cry "Elendil!" Video game references are the most frequent and generally occur with the least provocation. Mike makes jokes several times that hint he spent most of his teen years playing NES games, and jokes about more modern video games like ''{{VideoGame/Portal}}'' get brought up as well, though they have more of a WereStillRelevantDammit feel to them sometimes.
** It seems that Bill Corbett is a dyed-in-the-wool Whovian -- during the riff of ''DoctorWhoAndTheDaleks'', he was the one who made riffs about the movie not being canonical, and during a Christmas live-riff show was seen wearing the Fourth Doctor's scarf.
* ThrowItIn: If they think a joke is particularly funny the crew will leave their laughter in as opposed to editing it out. Sometimes it can go on for several minutes and almost derail the commentary.
* WhatCouldHaveBeen: The gyus wanted to riff ''[[http://www.imdb.com/title/tt0068248/?ref_=fn_tt_tt_2 Baffled!]]'' and ''[[http://www.imdb.com/title/tt0077942/?ref_=fn_tt_tt_1 Moment by Moment]]'' but they couldn't get the rights.
** Similarly, they tried to make a live show of ''Film/TheRoom'' but Tommy Wiseau wouldn't let them. (Apparently he called their office and yelled at whoever answered the phone.)
** They really want to live-riff ''Film/MiamiConnection'' but Alamo Drafthouse doesn't want to license the film to them.
