Common graced Jimmy Fallon's Tonight show stage last night and got up to some of Fallon's usual antics. The time, he faced off against The Roots' Tariq Trotter, or Black Thought, in a freestyle battle. Each artist were presented three randomly generated words that they had to somehow incorporate into a freestyle. Common spits some pretty cold lines, but the most fascinating is how he pronounces "snowplow." Check out the video above.
