@jamescousins @vishae @macgenie talking to a one pair household here ... and the pair is paired with all the devices - but only one at a time ... i think we live in an all or nothing world.

That said - @macgenie's comment (and the nature of this joke will obviously date it) ... reminded me of the statistician who always travelled with a bomb in his suitcase.

Why?

Because he was afraid of being blown up by a terrorist bomb - and at the time the odds were one in 10,000 that there would be a bomb on any plane he flew.

BUT

the odds that there would be TWO bombs on a single plane were 10 million to one.
