The Kindergarten-Out: Because Milady has nothing else better to do.

[Elin]

I know, right? Normally it takes an entire evening or perhaps a few days for things to go that far.

Further humor:

In the span of two hours, Breaking Bad goes from "I'm a dorky high school chemistry teacher with a normal life" to "Okay, I just killed 2 people and a pound of meth that I have to sell. How do I sell this meth and dispose of the bodies in such a way that it can't be traced back to me?"

Ellie: Looking back on it, it's kind of weird how much of a black comedy Breaking Bad is in its first season.
Brother: Heh, yeah. It's not really as dark in its first season.

*an hour passes*

Walt: Therefore it seems to me that our best course of action would be chemical disincorporation. Dissolving the body in strong acid.
Ellie: Oooookay, so I was wrong.
