There was once a chasid of the Rebbe, R’ Shlomo of Karlin, zt”l, who lived in a small town near Karlin, in a small broken-down house. This chasid did not have much of anything, but nonetheless he was happy with his lot. Every year, when the festival of Sukkos arrived, the chasid would wait until everyone else had built their sukkos, and he would then go around and ask for whatever they had left over. People would offer him a rotted board or a rusted nail, and it was from these leftovers that he would build his sukkah. For seven days, the chasid would sit in his sukkah and sing with great joy.
