Steven: I just remembered we have several partially decomposed totally rancid dump pumpkins left from Halloween.
Brock: Lets go throw those on Laurens doorstep!
John: Yeah, that way shit and decomposed pumpkin meat will explode on her personal property and cause the odor to permeate in to the brick and/or concrete, leaving her porch smelling of festering veggie shit.
