What a plonker!
Interestingly, the word "hello" hasn't always been a greeting. It was originally used as an expression of surprise. It started being used as a greeting with the invention of the telephone. One of the original greetings or salutations when answering a phone was "Ahoy-hoy!"
This is the version that Mr Burns uses in The Simpsons.
Look, you've got it all wrong! You don't NEED to follow ME, You don't NEED to follow ANYBODY! You've got to think for your selves! You're ALL individuals!
Yes! We're all individuals!
