"Darwins"
A shore party had been sent down to the planets surface to investigate after no one had answered the Enterprise's calls. What they found was shocking, and terrible.
Six bodies were scattered throughout the base. Frozen in place, displaying their last actions: a man showering fully clothed, a woman carelessly strangled, head engineer asleep at his post...
Spock being a member of the two man shore party received a transmission. Over the communicator Kirk asked, "What happened?"
Matter of fact and with no hesitation Spock replied, "From a logical perspective, stupidity."
A/N: Ever heard of the Darwin Awards? It's a sad type of hilarity. 'Nuf said.
