T.I. is insulted by the stereotypical scripts being pitched to him ("Look at this shit: gangster, drug dealer, rapper. I might as well be playing myself!") and looks to Ari to land him a more serious role. Specifically, he wants to play a supermarket employee who falls for an older woman and is jonesin' for that older woman to be Meryl Streep.
His requests are cut short when Ari is questioned by cops for sending feces by way of U.S. Mail (for one of his revenge plots, of course), and even T.I. is freaked out ("You are literally on some sick shit, Ari."). But it turns out Ari isn't under arrest, he's just in for a filthy surprise of his own.
