Jimmy just turned 10, and is very excited. He decides to test the members of his family to see if they remembered his birthday.

"Daddy, daddy, guess how old I am today!"

Jimmy's dad says "You're 10 Jimmy, happy birthday!" and gives him a hug.

Jimmy runs into the living room where his grandmother is knitting, and says "Grandmom, guess how old I am today!"

Jimmy's grandmom puts down her knitting needles, pulls down Jimmy's pants and starts fondling his entire package. She does this for a solid 15 minutes before she pulls his pants back up and replies "You're 10 years old Jimmy"

Jimmy is astonished. "Wow grandmom how could you tell?"

"Because I heard your father say it in the other room"
