When the Dazzling's PO box overflows with junk mail, Sonata Dusk gets fed up and decides that she wants out of the postal system entirely. Derpy, who is just as confused as usual, doesn't exactly help matters. As the post office refuses to comply with her demands, Sonata takes her cause to the streets, which goes about as well as one would expect.

Inspired by Seinfeld's "The Junk Mail".
