Sitting here bored at work and have just been reminded of a prank we used to play years ago (Stretchie - remember this?).
Our office window overlooks a busy bus stop, which just so happens to be within bluetooth range. I think you can see where this is going...
It basically involves searching for people who have left the bluetooth on their mobiles switched on & discoverable, then sending them something funny and watching their reaction as they try to figure out who the hell has just sent them the pic / message.
(One of the funniest things to send involves bending one arm 90 degrees at the elbow and using your mobile in your other hand to take a close-up photo of the inside of your elbow. Try it & see - works particularly well if you have hairy arms!
)
Anyone got any other good pranks to alleviate boredom in the office at a weekend?
