"Grandma?" said Jenny. "Yes Dear?" replied her grandmother.

"How old am I?" asked Jenny. "Well, honey..." replied the grandmother, and after a few moments of thinking she answered - "You're 13."

"Wow grandma! How did you find that out?" wondered Jenny.

"Well, Jenny, last year you celebrated your 12th birthday, so I made the math and reckoned you're now 13."

"Thank you grandma! You're so smart!" Said Jenny, and headed off to her grandfather.

"Grandpa, grandpa, how old am I?" asked Jenny.

"Well, Jenny...." Said the grandfather, and after a few moments of thinking said- "Take off your blouse...". So Jenny took off her blouse.

"Now take off your pants." said the grandfather. Jenny took off her pants with a bewildered look.

"Now your bra" said the grandfather. Jenny took off her bra, staying topless.

"And your panties" said the grandfather. Jenny took off her panties, now completely naked.

The grandfather examined her for a few minutes and then said- "Well, Jenny, you're 13!"

"Wow grandpa!, " Said Jenny, amazed, "How could you tell?"

"I heard grandma." said the grandfather.
