Killer Mike made his South Park debut with a scathing verse about mass incarceration.

“In here nobody knows you by the name," Mike rhymes. "You’re just a number, living under the bitch ass rules of a broken game."

The episode, “Hummels and Heroin,” premiered last night (Oct. 18) and focused on the opioid epidemic and mass incarceration. Who better to get to spit about mass incarceration than Killer Mike?

"They put me here to die, left me angry and alone. For the crime of being old, they threw me in this nursing home," he raps.

Take a look at Mike's verse below.
