After a 40th anniversary screening of the cult classic Monty Python and the Holy Grail, the five surviving members of the Monty Python comedy troupe — John Cleese, Michael Palin, Eric Idle, Terry Gilliam, and Terry Jones — reunited live on stage on Friday for a special Q&A at the Tribeca Film Festival.

The Q&A was moderated by Last Week Tonight host John Oliver, a longtime Monty Python fan who quickly embraced the anarchic spirit of the evening. As he asked the panel about their career-long commitment to a "healthy disregard for authority," John Cleese wandered around the stage, grabbed Oliver's question sheet, and stuffed his microphone into his mouth, as the rest of the Monty Python members repeatedly switched seats in an impromptu game of musical chairs.

When the Monty Python members did settle down, they spoke engagingly (and often coarsely) on a wide variety of subjects, including the filming of Holy Grail, their 2014 series of live shows at London's 02 stadium, and the state of comedy in general. "I think we don't talk enough about this awful political correctness," complained Cleese. "I do a lot of… I don't know if they're really racist jokes, but jokes like, 'Why do the French have so many civil wars? Answer: Because they like to win one now and again."

"I used to do these jokes, and then I would say, 'There were these two Mexicans,' and the room would freeze. And I would say, 'Why's everybody gone quiet? We did jokes about Swedes, and Germans, and Canadians, and the French. What's the problem about the Mexicans? Are they not big enough to look after themselves?' I find a lot of that very condescending."

The group also recalled the 1989 funeral of deceased Monty Python member Graham Chapman, during which Cleese delivered a legendarily irreverent eulogy. "Graham's whole ceremony was like that, because we were laughing and then crying, and then laughing and crying. It was as though the emotion was sort of flowing through us, instead of getting blocked, like it usually does in England," said Cleese. "When I was writing it, I got that idea, and I thought, 'No, I can't do that.' And then I thought, 'That's exactly what Graham would like.' Because one thing Graham could not stand was what he called mindless good taste."

John Oliver brought the evening to a close by praising Monty Python one last time. "We've established there's nothing less funny than sincerity, but you're the f----ing greatest," he said, to an enthusiastic standing ovation. Scott Meslow
