Friends star Maggie Wheeler, aka Janice Litman-Goralnick née Hosenstein, has revealed the inspiration behind *that* laugh.
Paired with the nasal 'OH MY GOD!' that made Chandler's crown jewels jump back inside his body, the iconic cackle was arguably one of the best parts of the 10-part series.
But where did the inspiration for Janice's irritating laugh that got even worse when she went into labour actually come from?
Speaking to Emma Barnett on BBC Radio Five Live, the Friends actress revealed that used Flipper the dolphin, Woody Woodpeck and Arnold Horshack of Welcome Back, Kotter to create the hilarious laugh.
"There was a character called Arnold Horshack and he used to laugh and he would say [laughs]," said Maggie.
"Then I grew up watching Flipper which was a fantastic show about a dolphin, and I was in love with that dolphin and of course the dolphin sounds like a dolphin...
"So I sort of say she's a combination of Arnold Horshack and Flipper and Woody the Woodpecker."
Arnold Hoshack was played by the late actor Ron Palillo, being described as an 'endearingly dim-witted character' in the 1975 sitcom.
Maggie went on to explain: "I don't know, I think Janice was some kind of conglomeration that I invented on the day.
"That laugh was a really organic life-saver, because Matthew Perry [Chandler] was so funny and I had to work with him and I knew he was going to crack me up. I knew that if Janice couldn't laugh on set or laugh at that moment, I was going to be in big trouble and that is why that laugh exists."
Despite only appearing in 19 episodes of the beloved US sitcom as an on-off love interest for Chandler (and Ross), Janice is the real unsung hero of the Friends cast, if you ask us.
