Amy Poehler's 'Difficult People' slammed for Blue Ivy-R. Kelly joke: Here's why it's extremely meta

There's a running joke through the pilot of Hulu's "Difficult People" -- the new caustic scripted comedy executive produced by Amy Poehler -- that has a big payoff at the end of the episode. It all starts when creator Julie Klausner's character (she plays a wannabe comedy writer named Julie) fires off a tweet that reads, "I can't wait for Blue Ivy to be old enough for R. Kelly to piss on her."
