TINY TIM
Alas for Tiny Tim, he bore a little crutch, and had his limbs supported by an iron frame! ... 'He told me, coming home, that he hoped the people saw him in the church, because he was a cripple, and it might be pleasant to them to remember upon Christmas Day who made lame beggars walk and blind men see.' ... Bob's voice was tremulous when he told them this, and trembled more when he said that Tiny Tim was growing strong and hearty. ... His active little crutch was heard upon the floor, and back came Tiny Tim before another word was spoken, escorted by his brother and sister to his stool beside the fire; ... even Tiny Tim, excited by the two young Cratchits, beat on the table with the handle of his knife and feebly cried Hurrah!
