Song writer Mark Devereaux accidentally calls millions of green Martians to invade Earth. No they aren't dangerous, just wise-cracking, intrusive, pain in neck, annoyances. No one can escape their distracting influence. It's up to Mark to figure out how they got here, and most importantly, how to get rid of them before they drive everyone crazy!
