The world will not end tomorrow.
The large heavenly body sent on its way to smash into the earth had a design fault (those pesky engineers had failed to test for all the Rumsfelt beloved 'unknown unknowns') and unexpectedly contained 0.000053 of a nanogram of neonic. It got lost on the journey, and in 2.7 million years will crash into and destroy the colony established on an earth type exoplanet orbitting a brown dwarf 5.1 light years away by Bayer employees escaping armageddon on earth.....................at which point the ghosts of certain individuals looking on will shout..................'gotcha!' See! We were right, you completely failed to test for THAT!
