When the young boy was asked by his father to say the prayer over the bread, he realized he didn't have his head covered... so he asked his little brother to rest a hand on his head until prayers were over. The little brother grew impatient after a few minutes and removed his hand. The father said, "This is important... put your hand back on his head!" To which the little boy exclaimed, "What am I???.. ..My brother's kippah?"
