Brian & Stewie

Brian is going through his safety deposit box at the bank and the two discuss a sweater, over which they begin to argue. As Stewie goes to leave, however, the door automatically shuts and locks, locking them in and causing Stewie to crap his pants. They try calling for help, but to no avail. Stewie proposes that he can’t leave his diaper as it is and they ponder about what to do, Stewie concluding that Brian has to eat his poop, at which Brian is repulsed. Brian claims that he’d rather shoot himself - drawing attention to a gun in his box and causing a struggle for the weapon. Stewie gets it and threatens him with the gun, until they realize that Stewie has a mobile phone with a low battery. Unfortunately, Stewie wastes the last of the battery on calling a sweater store. Enraged, Brian slaps him, telling Stewie to go away. Feeling guilty, Brian gives in and says that he will eat his poop. Stewie undoes his overalls and they take his diaper off. Eventually Brian forces himself to eat it, the sight of which causes Stewie to vomit. Eating the vomit also, though willingly, Brian then braces himself and licks his butt. After redressing, Stewie is tired and, as they go to sleep, they realize that the next day is Sunday and that they'll have to spend another day trapped.
