"Frinkcoin" is the 13th episode of season 31. It aired on February 23, 2020.



"Homer and Marge compete to be the topic of Lisa's "Most Interesting Person I Know" essay. Lisa instead chooses Professor Frink. While Lisa works on the essay, Frink develops a cryptocurrency, overtaking Mr. Burns' title of richest man in Springfield. With new fame, Frink struggles to know who his real friends are, while Mr. Burns schemes to take his title back."


The Simpson family are eating at The Lentil Institution, a vegan restaurant, kissing Lisa up to make a choice on her "Most interesting person I know" paper, but she chooses Professor Frink, devoting to helping the world through science.

At Springfield University, Lisa visits and interviews him. After explaining the story of his life, Frink says to Lisa he's developing a new cryptocurrency, Frinkcoin.

Frinkcoin becomes famous and Frink becomes the richest man in town, enraging Mr. Burns. Frink however feels empty insides so Lisa tries to help him, and he moves from his University office to Chicago, but still feels sad, so Marge suggests Homer takes him to Moe's.

Frink aces Moe's trivia questions and earns the respect and friendship of the barflies, while Smithers assembled a team to create Burns Coin. Burns is angry at Smithers cause he started calling him by names instead of Mr. Burns and he searches help at a support group.

Frink brings his new friends to at Springfield's finest establishments while Mr. Burns is more angry as the nerds for being late, but they created a formula to render all cryptocurrency worthless, but the calculations would take thousand of years, so he is going to break Frink's spirit.

Mr. Burns instills upon him the doubt that he would never know if anybody really likes him, or his money. In the final chapter of her interview, Lisa has Frink know of how cruel and ruthless Burns really is and to not listen to him.

Burns brings the equation in the center of town, in front of the Jebediah Springfield's statue to have people solve it in no time. Meanwhile, Frink tests his friends to see if they're really his friends, with all of them failing to do so.

A solution to the equation gets posted on the billboard and the person that solved it was Frink himself. Lisa and Frink find themselves becoming best friends, though Frink realizes he just lost all his money with the action. In the end he returns to the University and kisses the woman who he worked with there.
