The "rules" of the show
After a while, you can recognize the patterns or "rules" followed by characters on the show. Much of this is is plot driven and due to the fact that the show can only cover so many details in the allotted time and still have the stories resolved by the end of the episode. Also, it is "The Love Boat" and not the "Makes Logical Sense Boat," and I don't think the show would have survived without some of these rules:
1. If a man dresses like a woman, Captain Stubing will develop a sexual attraction for this man and won't be able to keep his hands to himself, even though that's not how he reacts to an actual woman.
2. Romances of the crew members will last only as long as the current cruise and will end as soon as the ship gets back to San Pedro.
3. Stalkers are harmless. Whether they're male or female, their advances will eventually be reciprocated.
4. Disguises, no matter how thin, will always fool the ones they're intended to fool, even if no effort is made to change someone's appearance.
5. On any cruise, there will never be more than three black passengers. They will all know each orther and gravitate toward Isaac and one will likely have had a past relationship with Isaac or will have a relationship with Isaac on the current cruise.
6. Jewel thieves are in abundance and target passengers on the cruise. Fortunately, most jewel thieves will return the jewels without ever being caught.
7. Passengers are likely to spill their life stories the minute they step on the ship, including details most people wouldn't talk about.
8. There's always a happy ending, even when there are stories that shouldn't be happy, like the time a boy has a terminal illness, but doesn't know it. He thinks his grandmother is the one who is dying and nothing changes or is resolved in the story.
9. Many characters seem to have a sixth sense on detecting when another character is available and when one is married.
10. When a person displays a pattern of lying, cheating, and deceit, the person is usually perceived as being a good person despite these flaws and is almost always forgiven, often immediately.
11. When a character is resistant to the advances of another, the person will change his/her mind at the end of the episode, despite no reason being given.
12. Characters who are performers on the show will delight their audience despite interjecting their personal problems into their performances, like the magicigan, the comedian, the two ventrilaquests, the singer/songwriters, the singer/piano-player, the guy and his fake bear, the ballet dancers, the consumer advocate, and the psychics.
13. No matter how angry, depressed, or betrayed someone is feeling, he or she will still take the time and effort to dress formally for dinner.
14. Members of the crew are highly regarded by the business community and are highly sought-after as employees.
15. If a job offer is made to a member of the crew, the amount of the annual salary will never be mentioned, but it will always be double what the person is currently making.
16. If you try to change cabins, you will find out the ship is sold out and there aren't any spare cabins.
17. Mexican orphans who don't speak Spanish very well are likely to be adopted by fellow passengers and the adoption process is very easy and probably instantaneous.
