Mr. Peanutbutter is one of the kindest and the most seemingly-happy characters on BoJack Horseman. Due to his fun persona, he often comes across as rather naive and simple-minded - similar to Todd. However, there is a surprising depth to his inner-world. His thoughts might seem simplistic, but they hold profound truths, as well.
Throughout the six seasons, he has married and divorced Diane, campaigned for governor, worked alongside BoJack on Philbert and starred in Birthday Dad. On this journey, he said some things that went down as some of the most memorable quotes in the series.
"Why Does It Suddenly Matter What I Want?"
Mr. Peanutbutter is a loyal and loving husband, but somehow, he always ends up getting divorced. In "Hank After Dark,", Diane is thinking about going to work for Sebastian St Claire in war-torn Cordovia. Mr. Peanutbutter obviously doesn't love the idea, but doesn't push for Diane to stay either.
"Why does it suddenly matter what I want?", he asks her. He is a typical codependent. In love, he lives to serve his partner.
"I Gotta Say I Am Having A Time Of My Life Being Depressed!"
In "A Little Even, Is All," Princess Carolyn wanted to make Mr. Peanutbutter a likable character again after the world has found out he had cheated on his girlfriend Pickles with his ex-wife, Diane, by creating a meme 'sad dog.'
The publicity stunt worked and he quickly became the national face of depression. The campaign seems especially ridiculous to BoJack since Mr. PB is such a cheerful guy.
"All I Ever Wanted Was To Be Your Friend, And You Treat Me Like A Big Joke."
Mr. Peanutbutter is not confrontational at all, but in "Let's Find Out," he finally stood up for himself after BoJack disrespected him yet again.
Mr. PB confronts BoJack, asking him why won't he like him. He disregards BoJack's jealousy by saying: "You're a millionaire movie star with a girlfriend who loves you, acting in your dream movie. What more do you want? What else could the universe possibly owe you?" Sad moments on the show, such as this one, show that Mr. PB is more than just a happy-go-lucky dog.
"He's All Talk, No Shooting You With An Assault Rifle.”
A big chunk of BoJack Horseman's unique humor comes from the fact that a lot of characters are animals, rather than humans. In "Old Acquaintance," Mr. PB translates a dog phrase into a human one:
"He's probably just razzin' ya. But he's a good dog. All bark, no bite. Oh, sorry! That's a Labrador expression. I guess in human terms it would be: he's all talk, no shooting you with an assault rifle."
"Doggy Doggy What Now?"
Just as Sarah Lynn's character in Horsin Around kept saying, "That's too much, man," Mr. Peanutbutter's ' catchphrase is "Doggy doggy what now?"
The writers have a knack for writing phrases that sound as if they were from an actual 90s sitcom. Mr. Peanutbutter says it when he first lands the job as the star of his very own sitcom by complete chance. He instantly charmed the whole crowd.
"Everybody Deserves To Be Loved."
As a friend, Mr. Peanutbutter loves to give pep talks and keep things positive. Due to trauma caused by Beatrice, BoJack feels undeserving of love.
His self-image is a mess and he is constantly crippled by anxiety and depression. Mr. Peanutbutter 's quote, "Everybody deserves to be loved," holds a deep truth and it's exactly what BoJack needs to hear when he hits rock bottom.
"Erica! Get Out Of Here With That Face!"
Erica is definitely among the all-time favorite running gags of BoJack Horseman. Erica is a character with no screen time. Mr. Peanutbutter usually spots her at parties and gets distracted by "some noteworthy aspect of her character presentation."
The running Erica joke is also one of the oldest, since Mr. PB spots her in the pilot already, saying: "Erica! Get out of here with that face!" The last Erica exclamation happened in the very last episode, "Nice While It Lasted."
"Are All Of My Breakthroughs A British Prog-Rock Band From The 70s? Because YES!"
Mr. Peanutbutter's way of communicating certain things is definitely another one of his most iconic trademarks. He likes to talk by giving answers to his particularly niche questions. They sometimes serve as an insight into his character: "Are my self-destructive patterns and unexamined cycles of codependency the popular Jim Carrey character The Mask? Because - somebody stop me!"
Bojack asks him whether this is the way he phrases all his breakthroughs, to which Mr. PB replies: "Are all of my breakthroughs a British prog-rock band from the 70s? Because YES!"
"The Universe Is A Cruel, Uncaring Void."
Unlike BoJack and Diane, Mr. PB never shows any signs of having an existential crisis. But one time, he tells Diane something oddly profound and simplistic: "The universe is a cruel, uncaring void. The key to being happy isn't a search for meaning. It's to just keep yourself busy with unimportant nonsense, and eventually, you'll be dead."
This quote proves that Mr. PB also gives existential topics a thought and that his life philosophy is pretty stoic.
"What Is This? A Crossover Episode?"
Throughout the series, Mr. Peanutbutter wanted nothing more than to get a crossover episode with his beloved friend BoJack. After all, the two rose to fame by starring in sitcoms with a very similar premise.
BoJack always hated the idea, but Mr. Peanutbutter's long-time dream finally came true in the last season. He was so overwhelmed by it happening, he broke down crying, saying this was the best day ever.
