Two little boys are talking after school. One says, "I know how to make money off the grown-ups. You just gotta know how." He trains his friend on the way to do it. The boy goes home and catches his mother coming out of her bedroom. He arches one eyebrow and says, "Mom, I found out your deepest secret." She turns pale, looks back at the bedroom, and says, "You did?" She runs to get him a $20 and says, "Keep quiet about this to your father."
When his dad comes home, he goes out and meets him at the car. He cocks an eyebrow and says, "Pop, I found out your deepest secret."
His dad looks up at the house, says, "You did?" and brings out a $20. "Here, and don't tell your mother."
The kid goes to bed $40 richer. The next day the handyman is fixing their sink and he figures, why not. He cocks his eyebrow and says, "I found out your deepest secret."
The handyman stares at him for a second, sets down his spud wrench, and says, "You did???" He spreads his arms and says, "Come give your daddy a great big hug!"
