"If it is someone you share a house with (students), Collect the biggest pile of dog shit you can, bag it and freeze it. Then place it strategically in their room, nice and hidden. Allow nature to do it's thing."
Thats a bloody winner that Mac!!!! Ill keep it fresh in the memory for any insidants i disagree with.
On the same lines, heard this on the radio.
Some women broke up with her boyefriend for cheeting on her. Before she left his flat she took a carton of milk, emptied half of it and then punctured it for added effect, proped open one of the ceiling tiles in the kitchen roof, stook it up there and replaced the tile. Nice!!!! nothin worse than gone off milk!!!
