If you throw objects off the roof trying to smash some zombies

"Fuck you fuck you!", You scream down at the masses of zombies, some of them look up at you, but most are chasing down victims, or eating dead body's. You notice a brick on the roof is loose, so you work it free. There is about seven zombies gathered around a dead body and eating it ravenously, a fairly easy target, you toss the brick, it glances off a zombie's leg, nearly knocking it down, it pays no heed as it bites and chews at a length of intestine.
