I break your door in I sneak in the basement It is my home now But you never find out 'Cause I am sneaky, I am the rat man I go up at night, and eat your cheese! Aaah! ♪ But one day you find out there is a rat man Inside the basement and you call the cops But the cops don't take it seriously So you call the Ghostbusters instead The Ghostbusters are ill-equipped They only have ghost-busting weapons But they should've brought a shotgun But I have a gun so I kill them instead Oh no, it's murder!
