Merton is one of the original Chatroulette users that went viral with awesome prank videos, and he has amazing talent! He originally rose to prominence back in March of 2010, which is when the press took a-hold of one of his videos and made it go viral. Basically, he sits at a piano and watches people flash across the roulette screen, and as soon as someone stops a moment to watch him he begins playing and singing a 100% improvised on the spot song that describes the person, typically in as funny a manner as possible. It’s quite entertaining! You can read more about Merton on wikipedia, but for now, watch one of his most popular videos below:
