From Doug Chaplin via James McGrath:

The modern day Mycenaean cyber-warriors devised a cunning plan to get into Troy. They sent the Trojans an email with a website address linked from the words “You’ll love this great plan to get rid of the Greeks”. When King Priam logged on, a lovely simple cartoon animation of a wooden horse began playing in the web browser. Unknown to Priam, as the cartoon played, a deadly virus was taking down Troy’s online defences and overriding all the security systems, CCTV and time locks on the city gates.

Before he died the priest Laocoon – picking up this activity on his smartphone – bewailed the fact that no-one listened to him.

He had distinctly warned the king to beware of Geeks bearing GIFs.
