Can't Kill Us lyrics

We're like roaches, we are everywhere You try to step on us, but we don't care You kill one of us, yet we multiply Why can't you understand, that we can't die? 'Cause you poison us, to make us disappear But still we come back, showing no fear I've got the will to survive, that's why I'm still free 'Cause you can't kill us all, so you can't kill me!
