Marshall and Lily worry that Lily will never fall pregnant. To allay their fears, the couple visit a specialist who bears an uncanny resemblance to Barney.

Earl sets out to mend his relationship with his father Carl by trying to cross number four off of his list: "blew dad's chance to be elected mayor." Four years prior, Carl ran for mayor to oppose the other candidate's plan to redirect aeroplane traffic away from the affluent part of town and towards Carl's neighbourhood. A misunderstanding caught on tape was broadcast as the opposing candidate's campaign commercial.

Earl wants to use his birthday to look back on all the good he's done over the past year, but at his party, everyone seems to want to talk about his past misdeeds instead.

Earl's list of misdeeds grows when Joy makes it very clear that he's not welcome at her wedding to Darnell, scheduling it for his birthday so that no one can celebrate with him. This leaves him with just one possible course of action.

Earl scratches number 56 off his list when he must return a prize-winning cat back to its owner after sabotaging a cat show in Joy's favour. Meanwhile, Randy forms an attraction with the cat's owner.

Earl decides to cross number one off his list: Stole $10 from a guy at Camden market. He runs into major problems though when he realises that he now owes him much more than the initial $10.
