Matthew Perry revealed the mind-boggling method he used to persuade Julia Roberts to star on Friends.
The sitcom's star told how the Pretty Woman actress had an unusual demand to sign off for a spotlight appearance in the 1996 Season 2 episode The One After the Superbowl Part 2.
The 53-year-old, who plays loveable Chandler Bing, explained the bizarre encounter in an excerpt from his upcoming memoir entitled Friends, Lovers and the Big Terrible Thing.
He wrote: "Julia had been offered the post-Super Bowl episode in season 2 and she would only do the show if she could be in my story line.
"Let me say that again — she would only do the show if she could be in my story line (Was I having a good year or what?), but first, I had to woo her, " the passage read, according to the Times.
Perry tried to charm Roberts by sending over "three dozen roses" with a note that read, "The only thing more exciting than the prospect of you doing the show is that I finally have an excuse to send you flowers."
He added: "Her reply was that if I adequately explained quantum physics to her, she'd agree to be on the show.
"First of all, I'm in an exchange with the woman for whom lipstick was invented, and now I have to hit the books.
"The following day, I sent her a paper all about wave-particle duality and the uncertainty principle and entanglement, and only some of it was metaphorical.
"Not only did Julia agree to do the show, but she also sent me a gift: bagels — lots and lots of bagels... Sure, why not? It was Julia f***ing Roberts."
Roberts plays Chandler's childhood classmate Susie Moss in the hilarious episode.
The pair reunite and begin seeing one another, only for Susie's true intentions to come to light during their date when she steals all of Chandler's clothes as payback for embarrassing her in the fourth grade.
