"Linc or Swim"
- Broken Aesop: The moral of the episode is, "It's better to spend time with your family rather than to spend time on your own." This is broken for 2 reasons:
- Lincoln is meant to be viewed as being in the wrong, despite the sisters ruining his experience. In fact, the only reason he didn't want his sisters to find out is because he got kicked out of every community pool because of them, even though he never entered any of them. So the episode's basically saying, "Even if your siblings get you in trouble and don't let you have fun, it's less boring than spending time with yourself."
- The sisters don't learn anything, nor do they realize that they ruined Lincoln's experience of being in a pool. So the episode is also saying, "If you ruin your siblings' fun, hog it to yourself, and don't apologize for it, then you should be forgiven because you are oblivious to your troubles and don't know any better," or worse, "It's okay to bother someone else and ignore them, because it's their problem, not yours."
- The Cameo: A lot of the seniors at the first community pool are based on elderly people from other Nicktoons. Specifically, Lou Pickles, Iroh, Ms. Bitters, Miss Fowl and Phil Shortman.
