By sheer accident, I came across a quote that had me looking up some telephonic history. It turns out that Alexander Graham Bell, inventor of the telephone (originally the "harmonic telegraph") originally proposed people answer the phone by saying "Hoy Hoy!", said to be derived from the maritime greeting "Ahoy!". It was Thomas Edison, his sometime rival inventor, who proposed the word "Hello". Indeed, it wasn't until around 20 years ago when a historian uncovered the first written record of the word "hello", in a letter written by Edison in 1877.
So I propose that we all take a leaf out of Monty Burns' book, and answer the phone with Bell's original "Hoy hoy!". Who knows - it might catch on second time around?
