    A first grade teacher was having trouble with one ofher students. One day she asked Johnny what his problem was. He replied, "I'm too smart for the first grade, my sister is in the third grade and I'm smarter than her ." The teacher took him to the principals² office and explained the situation to the principal¹.
    The principal told her that he would give Johnny a test, and if he failed to answer one question he would have to go back to the first grade and be quiet.
    The teacher and Johnny both agreed.
    Principal: "What is 3 x 3?"Johnny: "9"Principal: "6 x 6?"Johnny: "36"And 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 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 agree.
    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 gasps³ (气喘）but before he can stop him from answering Johnny says, "pockets"Teacher: "What does a dog do that a man steps into?"Johnny: "Pants"Teacher: "What starts with F and ends with K and means⁴ a lot of excitement⁵?"Johnny: "Firetruck"The principal breaths a big sigh of relief and says "Put Johnny in the fifth grade, I got the last 4 questions wrong myself
