"The Shit Storm"
fill a brown paper bag with preferably "loose" stool, i.e..diarrhoea.in the cover of night,slide the open end of the bag under their front door,so the open end is now INSIDE their house.Now,SLOWLY tread on the other end of the bag(the end OUTSIDE the house)until half has been transferred into their establishment. Now stomp on the last bit to give that inside "shit explosion" look. take the brown bag and get rid of it. They'll wake up to the shit storm!! funny stuff.ive done this 4 times already.Never gets old.
