Here is the first snippet from the Great Adventures of Slick Nick mixtape, HEAR NICK GO AT EMINEM?IN THE SECOND VERSE?AT ABOUT 1:35min.

“There lived a young man who was so outstanding, to make it interesting it’s me, Nick Cannon — Now here’s a little something that needs to be heard/Yo I’ma serve this clown, now/Word, Nick?/Word/I don’t know if I should hit him because he’s feminine Slick, excuse me Eminem why you lying on your d*ck?/Erectile dysfunction, you wanna get ’em up — I see your mouth moving but you soft, Teddy Ruxpin/I tried to holla at you at the BET show, but you were scared of the trouble/More security than the Pope/And while you was in your bubble, I was rolling dolo, any time your face is in the streets is some signs for promo/Oh no, there’s been a mistake, see my name is Slick Nick, not Shady Flakes/I’ma mop you up with my wop like it’s ’88…” (“I’m A Slick Nick”)
