I know...

A 3rd grader really wants the new Pokemon game, but needs thirty bucks to get it. He tells his friend at school about his problem and his friend says, "Look, there's this awesome trick you can do to get money whenever you want. Just go up to an adult, look them in the eyes, and say, 'I know.' You'll get the money in no time."The third grader has his doubts, but decides to try it out on his mom when he gets home.

So he gets home, walks up to her, looks her in the eyes and stares for a bit. She says, "What is it, Honey? Did something happen at school?"

He keeps staring at her and says, "I Know."

A bit worriedly, she goes to her purse, pulls out $20 bucks and says, "Listen, Sweetheart. There are some things you just won't understand until you're older, but it's important that you don't tell daddy. Okay?" The third grader can't believe it worked. He grabs the money and runs away to go try it out on his dad.

He finds his dad upstairs and tries it again. He locks eyes and says, "I Know." The dad has the exact same reaction as the mom. He pulls out his wallet, hands him $20 and says, "Don't tell you're mother. You'll get it when you're older."

At this point, the kid is ecstatic. He can't believe it actually works, and he has the money for his game. He's so excited that he decides to try it on the next adult he sees to get even more money.

Sure enough, the doorbell rings soon after, so the boy runs down the stairs and finds the mailman there. The boy locks eyes with him and says, "I Know," to which the mailman responds, "Well Shit! Then come give your Daddy a hug!"
