Find out what time this prick from McKinsey goes to take a shit. Before he gets in the trap remove the toilet roll, unravel some length and randomly apply Pritt Stick glue in various areas before throwing any granular material on it, the sharper the better, sand, sugar, glass, iron filings etc.. that'll teach the cunt to understand the meaning of granular when he's letting more blood than a bakers dozen of periods from a haemophiliac lesbian out of his arsehole., or you could just sprinkle lots of sugar between the gaps in his keyboard.
