Last December Mac Lethal went viral on YouTube with a video of him rapping a pancake recipe at breakneck speed over the beat of Look At Me Now.
This time the multitalented rapper - who has also worked as a freelstyling breakfast menu at SUBWAY restaurants - is back to take on internet trolls who can't spell to the beat of recent hit single Somebody That I Used To Know.
Specifically, he's come armed with two bright signs to explain the difference between YOUR and YOU'RE - a common error and a subject clearly close to his heart.
And apparently he can do grammar as well as he can cook pancakes - that is, extremely fast.
As he explains the difference ("Look, this one belongs to you / and this one is something that you are, it's true"), the technical brilliance of the Kansas City rapper is undeniable - even if words like 'possessions' and 'contraptions' aren't your usual hip-hop fodder.
