Hello, dear humans! Barthlomew J. Simpson here, with a very important secret: MUTANTS FROM SPACE INVADE SPRINGFIELD!
It's true, man! A bunch of slimy, horrible, totally gross and putrid monsters are invading the bodies of people living here and they want to build a weapon that will take over the whole planet! Pretty cool, huh?
Anyway, yours truly is the only one who can see them because of my x-ray glasses - so it's up to me to stop them!
I have to spray paint things, get radical on my skateboard, use my trusty slingshot, and just generally behave like a nuisance, man.
Plus, with bad guys like Nelson the Bully and Sideshow Bob getting in my way, it's a good thing I have the rest of The Simpsons to help me out!
So if you are a decent person, a patriot and someone who cares about this sad planet, you will do the right thing. Save the Earth!
