Corrected entry: Just before they leave the school, Sharkboy or Lavagirl say that the planet Drool is just outside the solar system. But they do not leave the solar system since they did not pass Pluto. They also happened to miss Uranus. They also happen to be travelling faster than the speed of light, since they pass all the planets in a matter of seconds, while light takes hours, and travelling past the speed of light is impossible without creating a black hole.

Correction: The planets do not orbit the Sun in a straight line so it would be easy to not pass all (or even any) on your way out of the solar system. And, according to our laws of science, travelling faster than light (even with a black hole and you cannot create one) is impossible. But, then again, so are LavaGirl's and SharkBoy's very existence. Who knows what can be accomplished with their science.
