The stranger's voice is angry about your computer habits. "You're spending too much time on Facebook," you're scolded over the phone.
If this doesn't make you rethink spending too much time on social media sites, then two young MIT developers have a second idea -- shocking you with electricity.
Robert Morris and Daniel McDuff, fellow PhD candidates at the MIT Media Lab, were both agitated by time they wasted on Facebook.
So they put their gifted brains to work, and came up with two bizarre remedies.
The duo developed a system where people were hired at $1.70 a pop to call and yell at them when they reached a certain social media time allotment.
But it's their second idea, called the Pavlov Poke, that some see a future in.
Hooked up to your computer, it delivers a slight shock to the user when he or she has spent too much time on certain sites.
Set into a keyboard rest, a simple jolt from their Pavlov Poke might be enough to break the hold.
"Our intention was to promote discussion about the addictive properties of social media," said Morris. "We haven't promoted the device as a real product because our intention was mainly to spark discussion.
"Also, shock methods can be misused," he added. "This was definitely a Don't try this at home!' type of project."
But, he said, at least two other outside groups are now actively trying to create versions.
