Physicist Stephen Hawking, frequently cited as one of the smartest people alive, is also pretty funny. As the first person John Oliver interviewed for Last Week Tonight's new "People Who Think Good" series, Hawking delivered a stark lesson about the nature of reality: There is no timeline in which Oliver will date Charlize Theron.
Although you may accidentally learn something—imaginary time is Hawking's favorite concept that not even sci-fi writers bother to understand—most of the interview is just Hawking roasting Oliver.
Oh, and warning us that the machines will one day surpass and possibly enslave us all. No big deal.
