When young David was asked by his father to say the evening prayer, he realized he didn’t have his head covered — so he asked his little brother Henry to rest a hand on his head until prayers were over. Henry grew impatient after a few minutes and removed his hand.

Henry exclaimed, “What, am I my brother’s kippa?”
