Garfunkel and Oates is a TV series based on the musical duo of the same name formed by Riki Lindhome and Kate Micucci. The series aired for one season on IFC in 2014.
The episode "Rule 34" involves Garfunkel and Oates auditioning a song for the children's puppet TV series Pumpernickel Place (Sesame Street) produced by Wee One's Television Laboratory (Children's Television Workshop). The producers of the show (sans creator Gil Gilliamson, absent for reasons of incarceration, but shown in a Jim Henson-inspired photo) have decided that puppet characters Schubert and Sockley (who appear in one poster titled "Together Again") will celebrate a same-sex marriage in an upcoming episode (as an analogue for the long-rumored romantic relationship between Bert and Ernie). Garfunkel and Oates perform their song over a short puppet montage (created by Viva La Puppet, who have worked with Katy Perry and Pee-Wee Herman) featuring the characters getting married as witnessed by their puppet friends made up of monsters, sandwiches, and bananas. As rainbows play a central theme in the song, they later wonder if it's okay that they named it "Rainbow Connection".
