13. Everything tied up
First thoughts: Who do you know with a landline phone that they actually use? Given the low probability that someone is still using this relic of the past, could we rubber-band our smartphone? Apart from the technical advances, this roommate thriller is just annoying – making it an excellent choice.
It's something Zen-like and thoughtful when an extraordinarily large number of rubber bands are wrapped around an object. And depending on how urgently you need to use the phone, the removal process can either be satisfying and uncomfortable – or extremely annoying. It's almost like a work of art that's too valuable to ruin.
