I have a fear that the doorbell will team up with the fridge, LED lights, and other IoT devices to overthrow us.
Imagine being held captive by your fridge and toaster...
You have to really watch those internet connected refrigerators - particularly those with a bar code scanner. They are cold and calculating.....
The toaster is a real hothead. You can watch him as long as you like, but he'll pop as soon as you turn your back.
Wow, I had no idea you were so punny :)
