I was once with Rebbe Shlomo (Carlebach) at a subway station in Berlin.  A disheveled, drunken man started shouting angrily at us, “You dirty Jews!”  I urged Rebbe Shlomo to leave, but instead he went up to this raving man and hugged him.  The man broke down and cried “I wish all the Jews were like you.” ~ R’ Yehoshua Witt
