The Grim Adventures of Billy & Mandy Season 6 Episode 11
When Mandy and Grim go to the warehouse store, Mandy notices that everything seems to be in order, lacking any presence of chaos. Hoss Delgado, spectral exterminator, arrives saying that everything has been that way since he started dating Eris, the goddess of chaos. Mandy assures Delgado he must break up with Eris to restore chaos, but fearing her temper, he is reluctant to do so. After failed attempts by Grim, Mandy, Billy, and Irwin to break their relationship, Delgado finally tells Eris the truth about he wanting to break up, and she complies by turning into a giant insect and devouring him.
