7. Eddie Kim's Plan To Kill A Witness With Snakes - Snakes On A Plane
THE PLAN: Gangster Eddie Kim beats the crap out of some dude in Hawaii and this brutal murder is witnessed by poor old Sean Jones. Kim decides to do what any self respecting gangster would and have the witness killed by smuggling a case full of venomous snakes onto the plane he is travelling on to Los Angeles, where the trial will take place. His goons give passengers leis which are covered in a snake-pissing-off pheromone so that they go crazy and wipe out everyone on the plane.
WHY IT'S STUPID: While this made the efforts to kill Sean Jones much more hilarious, surely it would have been better to just smuggle a bomb onto the plane? Or get an assassin onto the plane who could just shoot/stab/poison him? All this messing about with snakes must have taken ages to organise and given that he had people on the inside (the security guards at the airport) he surely could have arranged for a bomb to be placed in the hold of the plane, wiping out his witness. Admittedly, this would have cut the run time of Snakes On A Plane down to around 15 minutes, but that's not necessarily a bad thing.
