His mother has barely finished her lunch when her son Little Johnny bursts through the front door of the house with a huge smile on his face, having come home early from school.
Surprised to see him so soon, his mother asked, “Why are you home from school so early?”
Little Johnny says, “They let me go early because I was the only one who could answer a tough question.”
“Wow, really?” says his mother. “What was the question?”
“Who threw the eraser at the teacher?”
