Both of those stories are a special kind of stupid but the alligator one is almost unbelievable. I can see how a drunk might think that the fireworks stunt might go alright but jumping into a muddy bayou with a 10 ft alligator in it makes no sense unless they were filming the latest "Faces of Death" sequel.
And as much as these stories might amuse some people, they actually have nothing to do with Darwin or his theories.
