In the episode, Bob must take legal action after he slips on the sidewalk and needs to pay for surgery, and ends up under the care of Jairo, who attempts to heal him without a doctor.
Bob has been having trouble coming up with a "Burger of the Day" and when he takes a walk to clear his head, he slips in front of Jairo's Capoeira Emporium (from season 1, 'Sexy Dance Fighting').
With the "Burger of the Day" deemed as the main thing causing Bob stress, he decides not to put one up which upsets his family and Teddy.
Luckily for Jairo, he gets his old studio back after the kids threaten his landlord, Mr. Fischoeder, with their fake lawyer letter and blackmail.
(It almost feels like a meta note on the rigors of the creative process — as Redditors have pointed out, it's easy to imagine how this story idea could have come about in the writers room.)
