When the team attends an Oktoberfest, Fry discovers that the traditions he is familiar with have changed and rebels, Bender enters a sausage-making contest, and Leela deals with an apparent loss.
Fry is disappointed to discover that the celebration has become much more refined since the 20th century, and he gets intoxicated and performs "The Chicken Dance", embarrassing his fellow workers, particularly Leela, who breaks up with him.
A flashback shows that Fry had managed to pull himself out of the shredder in time, losing his clothes and a little bit of hair in the process.
The fall, having given Fry both amnesia and an enlarged Neanderthal-like brow, leaves him unaware of his past, and he joins the tribe.
The two warring sides are inspired by this act of affection and decide to end the conflict before Fry and Leela's memories are fully restored.
A new and much-less-refined Oktoberfest celebration is restarted and the episode ends as Fry sits back while Leela performs the "Chicken Dance", allowing her to embarrass him for a change.
