In case anybody hasn't caught this on TruTV, they are actually having real-life engineers try to replicate Wile E. Coyote's attempts to catch the Roadrunner. In the two episodes I have seen, they are batting about .500 - it almost seems that the stunts are cursed. Nothing big- just a 155mm Howitzer going off unexpectedly!

Or a crane almost going off a cliff because the boulder was just a little bit too heavy.
