A dentist was examining a new patient. “Oh, my” he said. “This is the biggest cavity I’ve ever seen. The biggest cavity I’ve ever seen.”
“Was that really necessary?” asked the patient.
“What do you mean?”
“I’m frightened enough as it is. Why did you repeat yourself about the size of the cavity?”
“I didn’t,” said the dentist. “That was the echo.”
Sometimes in life, one must just say it twice.
