Is It Rude to Talk Over a Film? MST3K’s Mary Jo Pehl on Pretty Much Pop: A Culture Podcast #45

We live in a commentary culture with much appreciation for camp and snark, but something special happened in the early ’90s when Mystery Science Theater 3000 popularized this additive form of comedy, where jokes are made during a full-length or short film. Mary Jo Pehl was a writer and performer on MST3K and has since riffed with fellow MST3K alums for Rifftrax and Cinematic Titanic.

Mark, Erica, and Brian briefly debate the ethics of talking over someone else’s art and then interview Mary Jo about how riffs get written, developing a riffing style and a character that the audience can connect with (do you need to include skits to establish a premise for why riffing is happening?), riffing films you love vs. old garbage, the degree to which riffing has gone beyond just MST3K-associated comedians, VH-1’s Pop-Up Video, and more.
