A happy couple...
- Rosemary is one of the kindest human beings on this earth. Hal is particularly impressed when she gives enough food to the poor and when she visits a group of children in a hospital, who have severe burns (though he didn't know it at first).
- Giving food to the poor also shows that despite having grown morbidly obese off her eating habits, Rosemary isn’t greedy. She’s gluttonous, yes, and enjoys eating until she’s past fullness, but she wouldn’t hesitate to give her food to someone more in need. This makes it funnier in a charming way when she eats the whole milkshake she was sharing with Hal - she wasn’t doing it to deprive Hal of food, she was doing it simply because she needed it for herself, with no malice whatsoever.
- After giving a "The Reason You Suck" Speech to Hal after suspecting that he is mocking her for constantly saying she is beautiful, Rosemary leaves and Hal becomes depressed, believing that his chances with her are ruined. The next morning, to his surprise and happiness, Rosemary appears at his door with breakfast, apologizing and inviting him to a meeting, apparently determined to give him a chance to prove he is telling the truth.
- Hal defending Rosemary from her father, accusing him of causing her low self-esteem (although he doesn't yet know Rosemary is obese).
- When she is about to have sex for the first time in her life, Rosemary is terrified of showing off her obese body in lingerie and then naked in front of Hal, but he encourages her. The next morning she wakes up with Hal incredibly happy.
- The transgender hostess. Hal not only sees her as beautiful, but as the pretty girl she is inside.
- Hal refusing Jill's invitation to spend the night with her, after realizing that he is really in love with Rosemary, and decides to look for his true love, regardless of her appearance.
- Cadence, when Hal's whammy has been removed and he can see that she is actually the Littlest Burn Victim.
- The first thing Hal says upon seeing what Rosemary really looks like? "Oh my god. You're beautiful."
- Hell, the ending as a whole.
- Rene Kirby, who plays Hal's friend Walt, is a literal walking Heartwarming Moment. Despite spina bifida forcing him to walk everywhere on all fours (which is also true for the actor), Walt is seen as happier and more successful than pretty much everyone in the movie and takes his handicap in stride; when asked why he needs rubber gloves to go to the bathroom during a road trip, he simply replies, "You ever walked through a truck-stop men's room on your hands?" His humor and personality also means he does quite well for himself with the ladies.
