A flat-chested young lady went to Dr. Smith about enlarging her tiny breasts. Dr. Smith 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 terrific D-cup boobs! 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 said, "Scooby doobie doobies, I want bigger boobies."

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

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

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

That is a classic in the making! Well done.
