The Simpsons is one of the most iconic sitcoms (well, animated sitcoms) of all time. It's hilarious, often topical, and full of brilliant satire. That said, it's certainly not without its emotional moments.

Many of its emotional moments have since become iconic pieces of television history because really, who honestly expected this amount of heart from an animated sitcom!? Those are usually reserved for scatological, and oftentimes downright offensive, humor.

But then again, that's exactly what elevates The Simpsons above its competitors. It's often a genuine look into the lives of 20th and 21st century Americans.

These are 10 scenes that never fail to pull on our heartstrings.

Do It For Her

Perhaps the most famous emotional moment in Simpsons' history is the iconic "do it for her" ending. It comes in "And Maggie Makes Three," an extended flashback sequence that details the birth of Maggie. Homer was forced to quit his dream job and return to his job at the Nuclear Plant under the sadistic eye of Mr. Burns, who places a plaque reading "Don't forget - you're here forever" in Homer's work station. Asked why there are no pictures of Maggie in the photo album, Homer reveals that they are where he needs them most - at work, covering up the plaque so it reads "do it for her." It makes our hearts melt every darned time.

Happy Birthday Lisa

"Stark Raving Dad" is a classic Simpsons episode not only because of Michael Jackson's cameo but because of the iconic ending which sees Bart singing a custom birthday song to Lisa. At the beginning of the episode, Lisa reminds Bart that he is always forgetting her birthday. When Michael Jackson (well, a gigantic mental patient who believes he is Michael Jackson, voiced by actual Michael Jackson) shows up in Springfield, Bart once again forgets Lisa's birthday, causing her to disown him as her brother. However, he makes it up to her by writing and performing "Happy Birthday Lisa" with "Michael, which instantly cheers her up. Maybe he doesn't hate his sister after all.

Mother Simpson

"Mother Simpson" is one of the most mature and melancholy episodes of The Simpsons. In it, Homer learns that his mother Mona isn't really dead and finally meets her again after 27 years. Despite her prolonged absence, the two quickly reconcile and grow close. Mona had to go on the run and leave her family behind after fighting against Burns's germ warfare, and at the end of the episode, she is forced to go on the lamb once more when the FBI discovers her location. Homer drives her to a secretive pick-up location and is forced to watch his mother leave his life yet again. He proceeds to sit on the hood of his car and stare at the stars, a beautiful image that remains on-screen throughout the end credits.

You Are Lisa Simpson

Season two's "Lisa's Substitute" is another revered episode of the show. In it, Lisa falls in love with her substitute teacher, Mr. Bergstrom. She finds both comfort and inspiration in him, as he actually encourages her intelligence. Before long, Bergstrom is taken away due to a job in Capital City, but before he leaves he hands her a note and tells her to open it in times of need or loneliness. When she opens it, she sees the words "You are Lisa Simpson" written on it.

Homer Cheers Up Moe

Alright, let's leave the Golden Era behind for a little bit and look at a more recent episode. This comes from season 20's "Eeny Teeny Maya Moe," which sees Moe finally finding love. As you can probably imagine, it doesn't go well. Enter a surprisingly heartfelt speech from Homer: "Sometimes, when you least expect it, you'll realize that someone loved you. And that means that someone can love you again. And that will make you smile." It's such a simple yet beautiful sentiment, and it means so much more coming from a total doofus like Homer Simpson.

Bart's D-

In case you haven't noticed, Bart isn't quite as smart as Lisa. But that doesn't mean we can ignore his accomplishments! In the episode "Bart Gets an F," Bart legitimately tries to do well in school and spends an entire snow day studying while everyone else has fun outside. Despite his best efforts, he still fails an important test and genuinely breaks down and shows remorse for failing. However, he is given a D- after making an obscure historical reference and for actually applying himself. This leaves Bart elated, and the episode ends with the family pinning his D- test on the fridge. You take your wins where you can.

Bart's Christmas Present

Bart is particularly hostile and rebellious in the episode "Marge Be Not Proud," as he steals a video game from the Try-N-Save. After being caught and having his crimes revealed, the Simpson family begin excluding Bart from various family activities.

Bart legitimately feels bad for his actions and grows concerned that Marge no longer loves him, so he decides to take action. He returns to the Try-N-Save and gets a nice portrait of himself for his mother, which he proudly reveals to her. Marge shows gratitude at his changed behavior and mother and son finally reconcile.

The Leftorium

When "Flanders Failed" sees Ned Flanders opening a store specifically for left-handed people brilliantly called The Leftorium. Jealous of Ned's success, Homer wishes for it to fail, which it proceeds to do. However, Homer didn't think through the realities of the situation and the Flanders' are plunged into horrible debt (which includes losing their house). Feeling remorse about his wish, Homer proceeds to tell all the left-handed citizens of Springfield about The Leftorium, causing them to flock to the store and making it successful. Sometimes Homer feels bad about his actions. Sometimes.

Bart Takes The Blame

If you need further proof of Bart loving Lisa, look no further than season three's "Separate Vocations." Lisa has a terrible day - not only does a career aptitude test recommend being a housewife, but Lisa's music teacher tells her that her fingers are too short and stubby to successfully play the sax. Lisa begins to act out and steals all the Teachers' Editions of the school books. Bart discovers that his sister is behind the expulsion-worthy offense and takes the blame for it. When she asks why he says that Lisa can't throw away her brilliant career prospects.

Remembering The Good Times

One more Lisa and Bart moment, because they're just too cute together. You know, when they're getting along. This one comes in season six's "Lisa On Ice," when Lisa is discovered to be a star hockey goalie. A sibling rivalry between Bart and Lisa quickly develops, and at the end of the episode, Bart is given a penalty shot against Lisa to decide the game. But rather than continue the rivalry, both Bart and Lisa remember the good times they have had as siblings over the years and decide to embrace, resulting in a tie game.
