Monica Geller has many flaws. She's a control freak, perfectionist, an obsessive cleaner, picky, and extremely competitive. She's also loving, persistent, an excellent cook, and fiercely loyal to her friends. And those good traits wouldn't exist without the less appealing ones, as proven by these nine times Monica's annoying habits actually saved the day on Friends. No, Monica's more bothersome traits didn't solve world hunger, or answer the mystery of how Ross got so many women to marry him. But, they did come in handy in saving Ross, Chandler, Joey, Rachel, and Phoebe from a few unfortunate situations over the years, and that's more than enough.
Friends ran for 10 years, ending with a total of 236 episodes, and Monica, just like the rest of the main cast of characters, was in every single one. Over the years, fans watched as Monica went from a type-A aspiring chef to a slightly calmer mother of two. Though her more obsessive traits (cleaning, cooking, control, etc.) were often played for laughs, they also made her one of the most valuable members of the Friends crew. If nothing else, she was definitely the most resourceful and the most productive. It's no wonder Monica's annoying habits saved the day on Friendsfrom time to time.
