During the shop segment, Deema gives Gil a nickname, named "Drummer Boy", which she calls him twice.
During the lunchtime song, Nonny is in the front behind Goby and Molly, but then he appears behind Goby and Molly just before the lunchtime song ends.
Nonny's right hand changes positions on his lunchbox, twice between shots.
In the final scene, Gil's hat disappear, then Deema's sunglasses, then at the end of the episode, both Gil's hat and Deema's sunglasses reappear.
Deema asking Nonny if he saw any of the band members playing a piano could be a take on the show Animaniac's segment Good Idea, Bad Idea. In one of them, the Good Idea was playing a piccolo while the Bad Idea was playing a piano which was too heavy and crushed the character playing it while marching.
