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 Na Nah Nah".

The little boy angrily 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 says to 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!" HAHAHAHAHA

Good one
