"Ear-sy Rider" is the premiere episode in Season 3, being the twenty-third episode overall.
Mort is holding a funeral for Horny Dave, the head of a motorcycle gang called the "One Eyed Snakes". After the ceremony, the gang goes to Bob's Burgers to have beers, much to Bob's dismay. After having wrecked much of the restaurant, Critter, the new leader of the "One-Eyed Snakes", pays for the damage and gives Bob a card which he can use to ask the gang for a favor in the future.
Meanwhile, the kids are crossing by a street corner which is often occupied by skateboarding teenagers after school. Louise taunts Logan, one of the teens, to the point where he grabs Louise's bunny ears and runs off. Louise, unable to cope with the loss, starts to act crazy and wears a hoodie as a replacement. She is determined to get her bunny ears back. When bribery fails, Louise begins to follow and stalk Logan in numerous desperate attempts to get them back. Logan is resistant because he believes that the bunny ears have given him good luck. She finally tattles on Logan to his parents. When his parents confront him, Logan tells Louise that he had them sent to the dumpster. When Louise tries to track them down to the waste management plant but it is believed that they are incinerated and she is too late.
This brings Louise to her breaking point as she plots revenge. She cashes in the "One-Eyed Snakes" card and the gang arrives to threaten Logan. He confesses to never having thrown the bunny ears away and pulls them out of his backpack to give back to Louise. The gang returns to Bob's Burgers to celebrate as Louise tells them food and drinks are on the house.
Having learned that their son was threatened, Logan's family gathers the neighbors and they all confront the "One-Eyed Snakes" in the restaurant. Linda gets into a fight with Logan's mom. When Critter tries to break up the fight, Logan's mom accidentally tears off Horny Dave's jacket from Critter and a standoff between the neighbors and the "One-Eyed Snakes" ensues. Critter, in an attempt to prove his leadership, plans to beat the neighbors up. Before the fight can begin however, Mudflap, Horny Dave's pregnant lover, goes into labor. Logan's dad is a doctor and takes charge of the delivery where everyone in the restaurant lends a hand. After the baby is born, Mudflap confesses to Critter that he is the child's biological father.
Everyone is at peace, except for Louise and Logan who were looking forward to the fight. But Louise is happy to have her ears back anyway.
