DENTIST BIG HOLE JOKE
"Open wider." requested the dentist, as he began his examination of the patient. "Good God !" he said startled.
"You've got the biggest cavity I've ever seen - the biggest cavity I've ever seen."
"OK Doc !" replied the patient.
"I'm scared enough without you saying something like that twice." "I didn't !" said the dentist. "That was the echo."
