Just a freestyle i made up
 

This shit is crazy,

messin' with ya cranium'
now i'm saddem hussein-in' em,
this rappin' is fun, aint even close to done
ya'll know im numba' 1, ya'll know im the champion
i take you to school, make you look like a fool,
sucka you just a tool,
ya'll know you cant top me, you cant stop me,
ya cant beat RD, ya cant defeat RD,
i spit hot fire, rap star no longer for hire,
got sick rhymes like chamillionaire,
on my way to bein a billionaire,
i see ya'll stare, but i dont care,
ya'll know ya love my rhymes,
ya'll know im gonna be the next on the New York Times,
create sick lines,
bust caps with nines,
ya'll know I'm a true OG,
yea ya'll know me,
im packin' heat, creatin rhymes that fill a whole sheat
raps as temptin' as a Lil' Debbie treat,
got my AK, now what ya gonna say
make rhymes all day, i earn my pay,
now im done, this rhymin was fun,
and always remember that im numba 1
