The crocodile's teeth, an attempt at creative writing

A story told by Ramam, with some inputs from me. He began the story saying there was a crocodile and something  got stuck in it's teeth. The crocodile wanted to remove it.  I asked him how to go about it and he suggested using a tooth brush. I said neither the crocodile has hands or tooth brush, We  had recently read a passage on invention of tooth brush, where earlier people used animal hair for the brush. So he suggested we use  tiger's hair and the lion could brush the teeth for the crocodile. The story ends with a simple " Thank you" and  "welcome" by the crocodile and lion respectively.
