A Superstore fan asked whether there was a lot of improvisation involved with filming and the favorite improvised lines.
He also said that he really enjoys improv singing, and then proceeded to make up a song for the Comic-Con panel.
Ash quickly turned the question to Mark McKinny because she said that he improvises for his character Glenn a lot.
Feldman added that McKinney improvised a lot of the songs that Glenn sings on the show. He said “the finger of the devil is poking through the phone” song gets a lot of attention and he hears that people ask about it a lot.
