In the second episode of the third season of Breaking Bad, Walter White arrives home with a pizza for the family. Unfortunately, Skyler—who just found out her husband makes meth—answers the door and won't let him in. Walt walks to the driveway and throws the entire pizza on the roof. It's a weird move on its own, but the pizza itself is bizarre, too. It's unsliced. Who sells an unsliced pizza? It's a topic that's been of some internet debate since the episode aired in 2010.
In an entirely different scene, Jesse is having a party and orders a pizza, which arrives unsliced. Badger explains to his confused friends that "they don't cut the pizza, and they pass the savings on to you."
These are two scenes that just feel like unique Breaking Bad quirks. But as we've come to learn from repeated viewings and analysis, nothing is a coincidence on Breaking Bad.
During creator Vince Gilligan's Reddit AMA , one fan asked, "Was Badger and Skinny Pete's conversation at Jesse's party about the pizzas not being sliced written in after the fact to explain how Walters pizza landed on the roof intact? Everyone knows a sliced pizza would have come apart."
As creator Vince Gilligan says of the unsliced pizza, it had to do with continuity and physics:
Yes! We had a long discussion before we shot the pizza on the roof scene about whether or not the pizza should be sliced—because, as all you physicists know, a thrown, sliced pizza would come apart due to centrifugal force or angular momentum (or something like that). And yet, you're right: no self-respecting pizza parlor sells an unsliced pizza. So we figured we needed to explain it (in the "They pass the savings on to you" scene), or else face our audience's righteous wrath!
Unsliced pizza: just another reason Breaking Bad is the best show on television.
