A Midsummer's Nice Dream is a great Simpsons episode with a well written storyline and a ton of very funny scenes. I really enjoyed seeing Tommy Chong and Cheech Marin on the show, their style of humour is so different from the Simpsons that putting them together seemed like a mistake waiting to happen, but it ended up fitting together quite nicely, the balance worked out and made this a very unique episode. I thought the side story was very weak, it took away from the originality of the main story too often and it simply wasn't very intriguing, if Marge helped the Crazy Cat Lady out the whole time and we actually got to see a change in the character that would have been fine, but instead we just see Marge turn in to a hoarder. I think the highlights of the episode was seeing the characters perform with Cheech and Chong, Principal Skinner and Chong made a hilarious duo because of how unlikely they were, and Cheech and Homer were of course a delight to see together, whether or not you're a fan of this comedy duo (which I'm not), you'll enjoy. A Midsummer's Nice Dream is a very fun Simpsons episode that had me entertained.
When Cheech and Chong come to Springfield and break up during a show, Homer decides to join Cheech on the tour, while Principal Skinner joins Chong. Meanwhile, Marge tries to help the Cat Lady to stop hoarding, but ends up taking away all of her stuff to her own house, making Marge turn into a hoarder herself.
