See I actually wanted to title this post "Childish Gambino freestyles..." but then I got to the point in the video where dude whips out his cellphone to read out his lyrics - and decided to instead go with "...raps..." to prematurely fend off the "how are you gonna call that a freestyle if..." comments. So yeah, dude whips out his cellphone at some point while rapping on Tim Westwood's show - possibly taking Sway's advice about kicking a written to heart/too far? Donald's got some bars though (Exhibit B: his Royalty mixtape).
