Little Johnny jokes

Little Johnny asks the teacher, “Mrs Roberts, can I be punished for something I haven’t done?”
Mrs Roberts is shocked, “Of course not, Johnny, that would be very unfair!”
Little Johnny is relieved, “OK Mrs Roberts, sorry, I haven’t done my homework.”

Little Johnny asks his mum, “Mum, do all fairy tales begin with ‘Once upon a time in a faraway land’?”
“No darling,” says his mother, somewhat distressed, “Sometimes, they can begin with ‘I’ve got too much work in the office tonight, I’ll come home later’.”
