The Contest & Prove It!

The Contest: Buster is entering the TV Schedule Magazine's contest for writing an episode for the Andy and Company Show. His friends decide to enter in the contest too with their stories styled like South Park (Buster), Beavis and Butt-head (Muffy), Dr. Katz (Arthur), the WWE (Francine and Binky), and Dexter's Laboratory (Brain) amongst other things. Five years later, they are 13 and watch for the winning episode to find out a girl from Canadian, Oklahoma named Holly Holland has won.*
Prove It!: D.W. becomes interested in science after she watches an episode of Nova. When Arthur will not take her along to the Exploratorium, a hands-on science museum, she makes her own Exploratorium with false explanations of real-life occurrences, such as why the sky is blue, or what the formula for water stands for. She challenges Arthur and the Brain to "prove it" when they say she is wrong, only to have to take her to the Exploratorium.
