Under the Prison

One of my seniors walks into the classroom.
Mr. C: Hey J, what’s going on?
J: I just got back from court.
Mr. C: How did it go?
J: They gave me 2 counts of life and 30 days.
Mr. C: What? That’s a long time.
J: I don’t know why they did that.
Mr. C: I don’t either?
J: They gon’ make sure I can’t get out.
Mr. C: It sounds like it.
J: If they could, they’d put me under the prison.
Mr. C: Ha.
