The Canine Mutiny is a great Simpsons episode with a very well written storyline and loads of very funny scenes.It is without a doubt one of the weakest episodes of the eight season,but it is also the sweetest and most emotional episode,revolving around Bart's relationship with Santa's Little Helper,any episode revolving around that is always a sweet one because Bart has shown without a doubt over the years that he cares about that dog more than he does any member of his family or friends.The episode also has one of my favourite quotes,and definitely my favourite Milhouse quote,I'm not going to write out the whole thing,but it's about a fish bowl ("why did I have the bowl?").The Canine Mutiny is certainly a weaker episode of the eight season,but it's still a really great Simpsons episode.
After Bart manages to obtain a credit card,he buys a bunch of really expensive things,including an outstanding and talented dog called Laddie.When all his credit card bought items are taken away from him,he pretends Santa's Little Helper is Laddie and he gets taken away instead of the new dog,a decision Bart soon regrets.
