Eminem has previously compared himself to Heath Ledger on “Deja Vu”, and it’s a pretty good comparison: both being incredibly talented, and plagued by their mental demons. In Heath’s case, his evil twin would be The Joker from The Dark Knight. People laughed at the idea of casting a gay cowboy as an iconic villain like The Joker, so Heath spent a month alone in a hotel room trying to get into character.

His commitment paid off, with his iconic performance being rewarded with an Oscar (unfortunately posthumously) for his effort, however, some believed he may’ve got a little too into character, unable to get The Joker out of his head, with the psychotic character’s presence ultimately being the cause of his drug overdose in 2008 (R.I.P.).

Eminem suggests that perhaps it was The Joker who signed the suicide note/ledger (Em’s intentional wordplay!), not Ledger (no note was actually left), inferring that the Joker got the better of Ledger, consuming him and ending his life. Eminem fears he’ll meet the same fate if Slim Shady were ever to get the better of him, which he nearly did back in ‘08 (both Ledger and Em O.D.’d the same year).

A shoutout to Insane Clown Posse, he pokes fun at one of the duo’s most ridiculed lines in “Miracles.”

There’s also could be wordplay involved with the way he said “ICP in this” – sounds like “ICPenis”, which would be even funnier because it’s almost a pun on Cool (Icy) and Cocky (Penis?)

This reference is most likely a shoutout, rather than a diss, as the beef was squashed a while ago.

Finally, this might be Em’s way of stating that the bitch he mentions is a she-male. The ICPenis, could be interpreted as a misdirect, “I see penis, bitch.” This would fittingly transition into the next line, “Cause you’re a attractive, but we ain’t attractable.”

After the skit in “Criminal”, Em raps

“die bitches, bastards, brats, pets, this puppy’s lucky I ain’t blast his ass yet”.

Looks like the pup’s luck ran out, since he got in the way of Em’s escape route.

While many fans thought this lyric was “not fair,” Rihanna clarified in an Instagram caption that the lyric was “nothing.” It’s also confirmed in the digital booklet.

That “someone” would of course be … Eminem himself! Em famously expressed this sentiment in the intro and hook of “Lose Yourself”.

In the “Monster” video, he reenacts the “Lose Yourself” video, where he raps about seizing the moment.

This is also likely a reference to his song “Sing For the Moment” from his fourth studio album The Eminem Show, where he raps:

That’s why we seize the moment, try to freeze it and own it
Squeeze it and hold it ‘cause we consider these minutes golden

The “poet” mention in the first line could also be a reference to a famous quote from the book and the corresponding film adaption “Dead Poets Society,” reading, “Carpe Diem, seize the day boys, make your lives extraordinary.”

Eminem started heavily fusing rap with rock back on The Eminem Show (although that definitely wasn’t the first time he did it).

He does the same thing on MMLP2, with most notable examples being “Rhyme or Reason” (where he samples The Zombies), “Love Game” (with yet another sample of a classic rock tune), and “Berzerk” (which samples Billy Squier’s The Stroke).

Rock is also slang for crack cocaine. This could be a slight hint at days of drug usage.

In the last episode, “To'hajiilee”, Jesse outsmarted Walt and in a panic Walt called Jack for support. In the panic he gave Jack exact co-ordinates to where he is, not realizing how suspicious that’d be

This is the moment where we as the audience realize that Jack is smarter than he seems. Part of the reason he really came to “rescue” Walt was because he knew there had to be something about that coordinate Walt gave him

It is impossible to accurately understand what he appears to say in “German”. A translation of his alleged German statement two lines later would come out to be “Wieso kann er nicht so böse wie Lu sein” (“Why can he not be as evil as Lu.”).

He yells this line in a manner similar to how Kendrick sometimes does in his own songs, but is most likely mimicking a scene from “The Downfall” which is often used as a meme, showing Hitler “reacting” to different things.

Can be seen as him mocking kendrick’s spanish lines on collard greens, implying those lines were similarly gibberish and people were “easily impressed.”
