A Texas man screamed "Fuck the alligators" before jumping in a bayou that his friends (and multiple signs) warned was full of alligators, and then got killed by alligators. The Orange County Justice of the Peace Rodney Price told CNN:

He removed his shirt, removed his billfold ... someone shouted a warning and he said 'blank the alligators' and jumped in to the water and almost immediately yelled for help.

Natural selection just doing its thing.
