April Fool's - how to make fake geeks panic

There's been some great April Fool's jokes over the years.
My favourite is definitely Sir Richard Branson's:
Although he was a day early - a mistake on his part due to being blown off-course (so the April Fool's joke goes both ways) Branson landed in a UFO-shaped balloon in a field outside of London in 1989 & emerged in a silver suit - freaking out the police & the crowd of onlookers who had gathered.
Brilliant & hilariously funny in the spirit of the day.
IOL's report of Somali pirates holding the internet for ransom by hijacking the Seacom cable, not as brilliant.
Of course, there are still going to be people who fall for it & panic about the end of the internet as we know it.
I'm still debating whether their report about Steve Hoffmeyer trying to play the hero by chasing 6 armed men down after a robbery, is an April Fool's joke. Unfortunately the article was published on the 31st of March...
