What do you call a rapper who’s also a DOCTOR?
MC Healer.
Listen up, you smooth-brain. This joke is all about wordplay, get it? A "rapper" is a musician, and a "doctor" is a medical professional. If you combine the two, you get "MC Healer". It's funny because "MC" stands for "Master of Ceremonies", and it's a common title for rappers. You probably didn't know that.
