Ozymandias - S5-E14
Trivia: The trousers that Walt lost in the desert during the first episode appear briefly when he is rolling the barrel with money.
Trivia: There is a scene in this episode where Walter angrily tosses a box of pizza in the air in such a way that the pizza exits the box and lands on his roof. Before filming this scene, the crew had wondered how many takes would be required to achieve the desired result. Bryan Cranston nailed it on the first try.

Trivia: Holly says to Walter "mama" after he changes her diaper. This scene wasn't scripted but Bryan Cranston kept going, realizing it was gold.
Trivia: There is an "alternate ending" to this series. It features Bryan Cranston and Jane Kaczmarek reprising their roles as Hal and Lois from Malcolm in the Middle, with the entirety of Breaking Bad being a nightmare that Hal just woke up from.
Trivia: There is only one bathroom in Walter White's house, and that is in the master bedroom.
Trivia: While filming The Avengers in Albuquerque, Samuel L. Jackson wanted to appear as himself in the background of Los Pollos Hermanos in an episode of this series, but was not able to make the time to do so.

Trivia: The floor tiles in the hospital are all white except for 2 blue/green tiles in the same pattern as the BR & BA tiles from the logo in the credits (00:13:00)
Trivia: When Robert Forster (Ed, or "The Disappearer") stops by the cabin to drop off supplies to Walt, he tells Walt that his (Walt's) house has since become somewhat of a tourist attraction, and a fence has been built around it. Funny thing is, in real life that is exactly what has happened to that house since Breaking Bad. Tourists come to that house and take photos, and the owners have had to put up a fence to keep people off their property. Before the fence was put up, some people went so far as to throw a pizza on the roof, like Walt did in a previous episode.
Chosen answer: I'm not sure how far you are into the show but he does eventually come up with a way to launder it (wont spoil it for you but rest assured, when he gets a lawyer the show gets much better!) and in the final season he also comes up with a way to give his children his money without the cops or the DA knowing it came from him.
