"Singing Telegram" joke

It was Schneider's birthday, and that morning there was a knock on the door.

"Telegram!"

He opened the door excitedly, "Is it a singing telegram?" Schneider asked the messenger boy.

"No, sir. We don't do singing telegrams anymore."

"I've always wanted a singing telegram. Can't you bend the rules and make an old man happy?"

"Sorry."

"Please," begged Schneider. "Today's my birthday."

"Oh, all right," said the boy, "Happy birthday to you. .. happy birthday to you. .. happy birthday dear Schneider. .. your sister is dead."
