A man and woman are having sex, and the young boy walks in on them and screams, "MOM!" The man starts laughing and the mother tells the man to go talk to him about what the boy had just seen. Later on that day, the man looks for him, finally finds him and goes in to the room to talk to him. He opens the door, and just stands there in shock, as the boy looks at him and says, "Not so funny when it;s your mom, is it?"
