Stephen Hawking isn't just smart, he's also hilarious. The celebrated physicist was the inaugural guest on People Who Think Good, a new segment on John Oliver's Last Week Tonight. During the interview, Hawking discussed a variety of topics including imaginary time, artificial intelligence, and the talk show host's non-existent chances with actress Charlize Theron. One of the highlights of the brilliant video involves Oliver asking if there is a universe where he is the intellectual superior, to which Hawking calmly ripostes, "Yes, and also a universe where you're funny."
