Lostpark, there was a story where the Chasam Sofer, who wanted to test the reaction of the talmidim, asked them, mit was kehrt man aus the stube? With what do we sweep out a room? As the talmidim were searching all over the Shulchan Aruch, a young talmid got up and said, with a broom. Sometimes the obvious is in front of us but we are afraid to say it.
