Airdate: May 2, 2010Brian and Stewie are at the bank with Brian putting money in his safety deposit box. Just as they’re about to leave, the bank closes and the vault’s doors close, leaving them trapped. It gets worse when Stewie gets scared by the doors closing and defecates in his diaper. Stewie tells Brian that he’ll get a rash if his poop isn’t removed and asks him to eat his poop. Brian refuses to do so, but then realizes that Stewie has his cellphone with him, which is low on battery. But rather than calling for help, Stewie calls a store to return a $3,000 sweater he bought. After the phone dies, Brian is furious at Stewie and slaps him across the face, which leaves Stewie to cry in the corner. Feeling bad for what he did, Brian reluctantly agrees to eat Stewie’s poop, followed by wiping Stewie’s butt by licking it. After he does it, the two decide to settle down and sleep, but realize that they’ll be stuck in the vault even longer because tomorrow is Sunday.The next day, Brian decides to take a bottle of scotch from his deposit box and Stewie joins in in drinking and dancing with him. While drunk, Stewie asks Brian to pierce his ear, which Brian does, but the pin gets stuck and results in Stewie getting a big, bloody hole in his ear. Stewie, still drunk, asks Brian about Cesar Millan, to which Brian says that dogs always live in the moment. Brian feels offended when Stewie says that he doesn’t live with purpose, to which Stewie rebuffs that he only made him eat his poop because it would amuse him. Horrified, Brian aims a gun from his deposit box at Stewie so he can kill him, but Stewie points out a security camera in the vault and Brian learns to his horror that his disgusting ordeal has been caught on tape. Stewie tries to give Brian a mercy kill with his gun, bit instead fires a bullet that ricochets all over the vault, while hiding from the bullet, the two apologize to each other.Later that night, Stewie takes some energy bars from his backpack and Brian reprimands him for keeping food from him. Stewie gives him a bar and the two settle down. Stewie asks why would Brian have a gun with him when he’s always spewing liberal rants of stricter gun control. After some hesitation, Brian admits he’s suicidal, saying Stewie is right that he doesn't have a reason to live, like other dogs do, and the scotch is there so he can have one last drink before he shoots himself in the head. Stewie cheers him up by saying that he gives him purpose and that he’s his only friend. Brian thanks Stewie for being his friend and he reads David Copperfield to Stewie while he falls asleep. The next morning, the vault’s door open and Brian carries a sleeping Stewie out.
