it would be eminem for sure, bu Da One, those are not even nearly the right lyrics for that song...

Yo, you might see me joggin, you might see me walkin
You might see me walkin a dead rottweiler dog
with it's head chopped off in the park with a spiked collar
hollerin at him cause the son of a bitch won't quit barkin
(grrrr, ARF ARF) Or leanin out a window, with a cocked shotgun
Drivin up the block in the car that they shot 'Pac in
Lookin for Big's killers, dressed in ridiculous
blue and red like I don't see what the big deal is
Double barrel twelve gauge bigger than Chris Wallace
Pissed off, cause Biggie and 'Pac just missed all this
Watchin all these cheap imitations get rich off 'em
and get dollars that shoulda been there's like they switched wallets
And amidst all this Crist' poppin and wristwatches
I had to sit back and just watch and just get nauseous
and walk around with an empty bottle of Remi Martin
startin shit like some 26-year-old skinny Cartman ("God damnit!")
I'm anti-Backstreet and Ricky Martin
with instincts to kill N'Sync, don't get me started
These fuckin brats can't sing and Britney's garbage
What's this bitch retarded? Gimme back my sixteen dollars
All I see is sissies in magazines smiling
Whatever happened to whylin out and bein violent?
Whatever happened to catchin a good-ol' fashioned
passionate ass-whoopin and gettin your shoes coat and your hat tooken?


there we go
