A second grade teacher was having trouble with one of her students. One day she asked Johnny what his problem was, and he replied, "I'm too smart for the second grade, my sister is in the third grade and I'm smarter than her too."

The teacher took him to the principal's office and explained the situation to him.

The principal told her that he would give Johnny a test, and if he failed to answer one question, he would go back to the second grade and be quiet.

The teacher and Johnny both agreed.

Principal: "What is 3 x 3?"

Johnny: "9."

Principal: "6 x 6?"

Johnny: "36."

So, it went on like this. The principal asked him every question a third grader should know. Finally, after about an hour, he told the teacher, "I see no reason why Johnny can't go to the third grade, he answered all of my questions right."

The teacher asked if she could ask him some questions. The principal and Johnny agreed.

Teacher: "What does a cow have 4 of that I only have 2 of?"

Johnny: "Legs."

Teacher: "What do you have in your pants that I don't have?" The principal gasped, but before he could stop him from answering, Johnny answered.

Johnny: "Pockets."

Teacher: "What does a dog do that a man steps into?"

Johnny: "Pants."

Teacher: What starts with F and ends with K and means a lot of excitement?"

Johnny: "Firetruck."

The principal breathed a big sigh of relief and said: "Put Johnny in the fifth grade, I got the last 4 questions wrong myself."
