Puffless really surprised me with the clever writing and hilarious moments! The episode has 2 main stories, one where Patty and Selma decide to quit smoking after they learn their father died from lung cancer, and the second is where Maggie goes on an adventure with the animals in her backyard.
The Patty and Selma story was very interesting to watch as this is something new we have never seen on the Simpsons, which proves that the new seasons can deliver smart and unique episodes. As the episode progressed, it was very intriguing to see how Patty and Selma dealt with giving up on smoking. Their story was filled with hilarious moments, although, I did think the ending was very weak, and they could have created a better ending, but the beginning and middle saved the episode.
The Maggie story was also quite funny, and was a cute and nice addition to the story line of the episode, and ended really nicely.
Overall, I believe the episode deserves a 9 out of 10 because it had a strong beginning and middle with hilarious jokes and 2 great story lines, but I think the ending for Patty and Selma's story could have been stronger.
