An 8 year old boy walks home from school each day past an 8 year old
  girls house. One
  day as he is passing by, carrying a football, he can’t resist taunting
  the girl. He holds up
  the football and says, “See this football? Football is a boys game,
  and only boys can have a
  football!”. The little girl runs into the house and cries to her
  mother, “I want a football!”
  Being a woman of the 90’s, her mother runs out and gets her one.
  The next day the girl is waiting for the little boy and he rides up on
  his bike. She holds up
  the football, “Nah Nah Nah Nah”. The little boy angryly points to his
  bike and says, “Oh
  yeah, well this is a boys bike and only boys get boys bikes and you
  can’t have one!” She
  runs in to mom and the next day is waiting for him on her new boys
  bike.
  The little boy gets furious and pulls down his pants, and pointing to
  his most private of
  parts says, “Look, only boys have these and your mom can’t buy you
  one!!!”. The next
  day he walks by and asks her, “Well, I guess I showed you!” to which
  she promptly pulls
  up her dress, points to her parts and proclaims “My mother tells me
  that as long as I have
  one of these I can have as many of THOSE as I want!
