Since Jon Stewart announced he was stepping down from his role as host of The Daily Show last week, there's been a storm of speculation about who could be his replacement. John Oliver, who earned his own show on HBO for his work on The Daily Show, told Jimmy Fallon about his own idea for who could fill Stewart's chair — how about a hologram of John Stewart? As Oliver explains, if they can do it for Tupac, they can do it for Stewart, who must have said every word in the English language during his 16-year stint on The Daily Show.
