A common plot device in the world of my comic strip "Maxwell Silver Hammer" is the pop culture-referencing dream sequence - often, when I want to do a parody that's too outlandish for the strip's universe, I'll set it in a dream instead. It's allowed me to get a lot more in-depth with some of my parodies, including transplanting the MSH characters directly into the worlds of certain movies or TV shows.
Here's an example inspired by some recent discussion being made on the Agony Booth forums. I came up with MSH stories centering on all three of the Batman movies released in the 1990s - a 1992 story sees Michelle upset upon discovering Joel's secret crush on Michelle Pfeiffer in Batman Returns, while 1997 has Joel writing a scathing analysis of Batman and Robin for his Film Analysis class. But 1995 uses a dream sequence to put the characters directly in the universe of Batman Forever, with Joel as Batman, Aaron as Robin, Jocelyn as the Riddler, Michelle as Chase Meridian, and Steve as Two-Face.
(By the way, the MST3K silhouette in the Bat Signal is a reference to a gag I have in mind where Joel as Bruce Wayne asides to Aaron as Dick Grayson that he altered his logo "after watching last year's Turkey Day marathon".)
