Mr Burns who always answers the phone with Hoy Hoy!
Homer Simpson with Edison who invented what we all use on the phone
Mr Burns in the Simpson's always answers the telephone with the salutation "hoy hoy" ..Which was the greeting that Alexander Graham Bell gave originally to the telephone.
Little do we know that Thomas A. Edison came up with the salutation "hello"...Which is used all over the world today. It shows how old Burns is. He learned how to use the phone from Bell!
So Homer Simpson who re-invents the six legged chair and the electric hammer...also uses along with the rest of the world Edison's other invention
""hello""
....Amazing huh?
