<human>: (This is not my story, but my sisters)
Backstory: My sisters and the Douche bag (DB for short) moved in together, and his pet dog (This is important) The DB couldn't hold a job and keep up with his half of rent, my sister got sick of it and kicked him out. The DB managed to steal a large amount of video games before leaving. 

The Revenge: Due to the fact the DB couldn't hold a job, he couldn't take care of his dog. His parents got sick of his crap, took the dog and gave it to a well known Animal shelter. The DB let it slip that he had lost the dog, so my sister did some research and found the dog (She had loved the dog, and missed it after they broke up) She went to go pick up the dog and it is now in her care.
