Two small jokes here.
A kid comes home early from school, and catches his mother rubbing her crotch saying "Oh God, i need a man, i need a man". He catches his mother doing this several times. A few weeks later, he comes home early and sees a man on top of her. Thrilled, the boy runs to his room, closes the door, and starts rubbing his crotch saying "Oh God, i need a bike, i need a bike!"
A little girl is riding in her minivan with her mother. She says to her mother, "Hey mom, Daddy has a penis like a peanut!" Her mom, amused, says "You mean theyre small?" To which her daughter replies, "Nope, theyre salty!"
