Professor Stephen Hawking has presented the winning University Challenge team with their trophy - and revealed he is a long-time fan of the show.
Oxford's Balliol College beat Wolfson College, Cambridge, by 190 to 140 in the final of the BBC Two show.
The series was a hit on social media, in large part due to fan favourite Eric Monkman, who captained Wolfson.
Despite his team's loss some took to Twitter to describe the 29-year-old as the "people's champion".
Host Jeremy Paxman told Wolfson they had been "entertaining".
Professor Hawking told the two teams: "I have said in the past that it is not clear whether intelligence has any long-term survival value - bacteria multiply and flourish without it.
"But it is one of the most admirable qualities, especially when displayed by such young minds.
"Many congratulations to both teams but especially to Balliol College Oxford on becoming series champions on University Challenge, a programme I have long enjoyed."
It was only the second time in the quiz's 55-year-history that the trophy presentation had taken place outside the studio.
In the segment, Paxman congratulated the winners and told Wolfson there was "no shame in being runners-up".
Balliol then toasted their win with glasses of port.
Oxford colleges had lost to Cambridge for the past three years - until the 2017 final, broadcast on Monday night.
