He’s saying that when he’s rolling up a blunt in his car he gets a bit messy. He spits the same line as on the second track ‘Scarface’ of this album.

After so many awesome rhymes, anyone would guess that the rapper is on a roll.
i.e. He’s going berserk. ‘Berzerk’ is the 2nd single off ‘MMLP2’ by Eminem, again hinting at influence.

Eminem has made total 8 studio albums (Exluding D12 albums and bad meets evil). Out of them, excluding Infinite, the other 7 are platinum.
Eminem said that he would never completely retire. He’ll probably produce tracks or be related to rap in some other form. However, most of the people think that Eminem still has plenty of music left in him.

Eminem pistol-whipped a bouncer who was kissing his wife-then Kim. This started a lawsuit. Around that time, Eminem was involved in many lawsuits.
He has some references to that incident in many of his songs, especially from ‘The Eminem Show’. He made this skit for the incident.

Till 1999, Eminem represented the 313 but now many says that he represents Hip-hop. That is surely a very big transformation.

After his first album ‘Infinite in 1996’, Dr.Dre produced 3 tracks in Eminem’s album ‘The Slim Shady LP’ in 1999.
Dr.Dre made a song ‘Still D.R.E’ which mentioned that he signed Eminem. That’s what made him even more famous.

Eminem’s dad walked out when Eminem was born..
His mother was a drug addict. He has tackled his parents in many of his songs.

Cannibus reads all this out from his notebook. He admits he wrote all the rhymes. Here.

Here, after Dizaster was done with his rhymes, Bis admitted that he wrote all his rhymes and claimed that he was freestlying. He pulled out his notebook.

Some people feel Eminem has really twisted, evil music — leading to the comparison to Osama bin Laden.

Some think he is the next music phenomenon or maybe even a pop star, hence the comparison to Madonna.
