Did anyone else ever think the Magic School Bus is ridiculously overpowered? It exists outside the constraints of physics, having in one episode eliminated friction so Ms. Frizzle could show everyone what baseball would be like without physics. It also manages to fly across the solar system in mere minutes, and enabled the students to walk across the surface of Venus and wander the vacuum of space with little protection or discomfort. If I remember correctly, they even went ridiculously close to the sun and survived completely unharmed.
It's also driven by an iguana.
