Haha kk!!
So one day, a boy and a girl are playing outside in the playground.
The boy's pants fall off, and the girl ask, "What is that?"
So the boy goes home and ask his dad, "Dad what is this?"
His dad replied, "Son, that is your truck, you park it in the girl's garage!"
So the next day, the boy and girl are playing outside again, and this time, the girl's pants fall off.
The boy asked, "What is that?"
So the girl goes home and asked her mom, "Mom what is this?"
Her mom replied, "That is your garage honey. What ever you do, don't let a boy park his truck in your garage!!"
Finally, the next day, the girl comes home with her hands all bloody....
And her mom asked, "Honey, why is your hands have blood on them??"
The litle girl replied, "Well Timmy tried to park his truck in my garage, so I ripped his two back tires off." ..............
The End
I'm pretty sure that's how the joke goes. My friend told me it like a long time ago haha.
