Arcade Fire - Accidents lyrics

An old man has a heart attack in the movie theater While my friend calls an ambulance Buster Keaton's dancing I wait for the punchline But it never comes Two blind kids in wheelchairs are crossing the street And they get hit by the ambulance Because the light was green And I wait for the punchline But it never comes Promised you that I'd be true And now chandeliers are crashing down to the ground Waitresses drop their trays Trains derail with pa**engers While mother snakes eat their young The water pipes in this town Burst and flood the living room The firetrucks lose their way home And crash into the hospitals We're causing accidents Me and you We're causing accidents Me and you Where does a promise go When you pretend it isn't there? Do we really think that it could just disappear?
