Title: A Flea In Her Dome
This is a parody of the play A Flea In Her Ear.
In 1996, a Garfield strip ran in newspapers about an angel donut and a devil donut appearing to him. This is very similar to the scene in "The Donut of Shame" when the angel/devil donuts appear to Patrick.

When SpongeBob crossed the beams in "The Krusty Plate" and it resulted in an explosion, it is a reference to the end of Ghostbusters.
