Little Johnny came home from school looking upset.

His dad asked, “What’s wrong, son?”

Johnny sighed, “I got an F in arithmetic.”

“An F? How come?” his father asked.

“Well,” Johnny said, “the teacher asked, ‘How much is 2 x 3?’ and I said ‘6.’”

“That’s right!” said his dad, confused. “So why’d you get an F?”

Johnny shrugged. “Then she asked, ‘How much is 3 x 2?’”

His dad frowned. “It’s the same thing!”

Johnny nodded. “That’s what I said… but apparently, the teacher doesn’t like being told she’s flipping stupid questions!”
