it's my life

Little Johnny missed his final exam due to the flu, but he'd done so well during the year that the teacher suggested to the principal that they gave him an oral exam to make up for the test he missed.
The principal agreed so they called Little Johnny into the office and explained to him what they were going to do.
Then the teacher asked, "Johnny, what does a cow have four of, that I only have two of?" Little Johnny replied, "Legs."
The teacher asked, "Johnny, what do you have in your pants that I don't have in my pants?" Little Johnny replied, "Pockets."
The teacher asked, "Johnny, what is the capital of Italy" Little Johnny replied. "Rome."
The teacher turned to the principal and asked, "Should we pass him?" The principal replied, "Better not ask me, I got the first two wrong"
