Kevin Hart—little man, big star—took on James Corden—big man, little star—in a rap battle for the ages. Much like in Corden's surprisingly awesome rap battle against David Schwimmer, the two dropped bars and burns, Hart killing it with the line, "I admit people are nice to your face, until they get home and realize you're not Ricky Gervais." There were short jokes galore, with Corden offering Hart a stepping stool and firing off with “You might Think Like a Man, but you’re built like a boy.”
