That laugh is one of the greatest laughs in history.
There's just something so immensely satisfying about watching celebs sit down and enjoy YouTube and viral videos just like us (just like us!). Back in 2011, Rhymes challenged fans to try and do his lightning-fast rap from his song with Chris Brown 'Why Stop Now' and submit videos of their attempts in his Spit Like Busta Rhymes contest. This is Busta watching said submissions and simply having the best time.
