A mom is driving her little girl to her friend’s house for a play date.
“Mommy,” the little girl asks, “how old are you?”
“Honey, you are not supposed to ask a lady her age,” the mother warns. “It is not polite.”
“OK,” the little girl says, “how much do you weigh?”
“Now really,” the mother says, “these are personal questions and are really none of your business.”
Undaunted, the little girl asks, “Why did you and Daddy get a divorce?”
“That’s enough questions, honestly!” The exasperated mother walks away as the two friends begin to play.
“My mom wouldn’t tell me anything,” the little girl says to her friend.
“Well,” said the friend, “all you need to do is look at her driver’s license. It’s like a report card; it has everything on it.”
Later that night, the little girl says to her mother, “I know how old you are—you’re 32.”
The mother is surprised and asks, “How did you find that out?”
“I also know that you weigh 140 pounds.”
The mother is past surprise and shock now. “How in heaven’s name did you find that out?”
“And,” the little girl says triumphantly, “I know why you and Daddy got a divorce.”
“Oh really?” the mother asks. “Why?”
“Because you got an F in sex.”
Explanation: This joke humorously highlights a child’s innocence and literal interpretation of information. The little girl, guided by her friend, finds her mom’s personal details on the driver’s license. She misinterprets “Sex: F” (indicating female) as a failing grade, concluding that’s why her parents divorced. The humor lies in her naïve misunderstanding of adult concepts.
