''Tikki tikki tembo-no sa rembo-''''chari bari ruchi-pip peri pembo!'' Three decades and more than one million copies later children still love hearing about the boy with the long name who fell down the well. Arlene Mosel and Blair Lent's classic re-creation of an ancient Chinese folktale has hooked legions of children, teachers, and parents, who return, generation after generation, to learn about the danger of having such an honorable name as Tikki tikki tembo-no sa rembo-chari bari ruchi-pip peri pembo. ''Tikki Tikki Tembo'' is the winner of the 1968 Boston Globe - Horn Book Award for Picture Books.
