when i was about 11 or 12 years old, i tried to call a friend but accidentally dialled the wrong number. and instead got a very strange tone i've never heard before. i figured i've stumbled onto some kind of alternate dimension or secret military line, and would periodically call that number to see if the tones change... but it was always the same. it wasn't till much later that i learnt it was a fax line.
