Joseph Ducreux/ Archaic Rap

On knowyourmeme.com there is an article about Jospeph Ducreux/ Archaic Rap. This is a meme made famous on the website 4chan. It is taken from a self portrait of Joseph Ducreux, an eighteenth century French artist known for his unorthodox poses.  On 4chan they took one particular portrait of him and put text of a famous rap but as one would say it in the 18th century. I love this meme even though I know nothing about rap because I can't imagine a guy like this trying to rap in that manner around other eighteenth century folks. It is a very original meme but it's sometimes hard to get the rap song they may be referring to.
