"CRAZY HANDFUL OF NOTHIN'"

SEASON 1 EPISODE 6
Walter White, back in business with Jesse Pinkman, enters the RV and surveys the damage. He sternly gives Jesse a lecture, telling how things will be from now on. He tells him that he wants to be the "silent partner," his "realm" is only the chemistry and Jesse's is the street. As far as customers, Walt wants nothing to do with them "No more bloodshed." This scene is intercut with shots of a bald man calmly walking through a group of bikers on a street littered with smoldering debris, various car alarms blaring. He is holding a white bag with a red stain on it. As we pan up and his face is revealed, we see that this bald man is actually Walt and we are in a flashforward.

"CAT'S IN THE BAG"

SEASON 1 EPISODE 2
Walter White and Jesse Pinkman first use hydrofluoric acid in Season 1 to dispose of the corpse of Emilio Koyama. However, Jesse disregards Walter's instructions about using a plastic container, instead choosing to pour the acid onto the body placed in a bathtub. This results in the acid dissolving through the bathtub and the floor, scattering Emilio's liquified remains into the hallway.

"PILOT"

SEASON 1 EPISODE 1
A man wearing nothing but his undergarments and a gas mask careens his RV down a desolate highway in the New Mexico desert. In the passenger seat, another man is passed out, also wearing a gas mask, his head on the dashboard. Two bodies slide across the RV floor until the vehicle veers into a ditch. The hyperventilating driver, Walter White, climbs out, dons the shirt still hanging off the side view mirror (his pants are long since gone), then re-enters the van to retrieve a video camera, his wallet, and a gun. He records a cryptic, handheld farewell to his wife and son as sirens can be heard in the distance. He then places the camera alongside his wallet, walks onto the road, and awaits the approach of the emergency services, gun in hand.

"CORNERED"

SEASON 4 EPISODE 6
White explains to his wife Skylar that their family is not in danger of being killed by his enemies and that he is the one his enemies should fear, proclaiming “I am the one who knocks.”
This scene is probably the most famous out of all the episodes from the five seasons of Breaking Bad as the quote; “I am the one who knocks” has been referenced over many platforms and mediums such as the television show 'The Simpsons' and has made a name for it's self through the use of memes also.
