 * I don't think I've ever seen this episode. Wow.
 * Brain's lucky none of his friends were impaled with the model plane when it crash landed.
 * Arthur's skin must be pretty robust -- you try yanking a scared cat off of your head without doing damaging your scalp.
 * How does the bobbin roll away? It seems to be flat (except in D.W. Rides Again.)
 * Brain's remote control for his plane looks just like the one he used for his tooth extractor-- it's probably the same one he used in his robot cat, and his robot father that matter
 * This is basically the average Season 4 episode. It's alright.
