A really old one that continues to make me laugh...

A somewhat flat-chested young lady went to Dr. Findlay about enlarging
her tiny breasts.

Dr. Findlay advised her, "Every day after your shower rub your chest and
say, Scooby doobie doobies, I want bigger boobies."

She did this faithfully for several months and it worked! She grew to a D
cup size!

One morning she was running late, got on the bus and, in a panic, realized
she had forgotten her morning ritual.

Frightened she might lose her lovely boobs if she didn’t recite the little
rhyme, she stood right there in the middle aisle of the bus closed her eyes
and softly said, "Scooby doobie doobies, I want bigger boobies."

A guy sitting nearby looked at her, "By any chance, are you a patient of
Dr. Findlay?"

"Why, yes I am... How did you know?"

He leaned closer, winked and whispered, "Hickory dickory dock..."
