Actress Maggie Wheeler aka Janice, Chandler Bing's annoying on-again, off-again girlfriend on Friends, has revealed her favourite behind-the-scenes moment from the popular TV show.

Wheeler made quite the impression on Friends' fans during her 19 episode-run with her nasally voice, obnoxious laugh and infamous "Oh my god," catchphrase. The actress who made the recurring role famous, recently revealed one of her favourite memories from the show happened during a taping in the fifth season.

In the episode, it is revealed Janice hooked up with Ross, played by David Schwimmer.

Wheeler told Australia's Today Extra, "Whenever I was on the show I had to make a secret entrance so it was a huge surprise for the audience," she said, recalling the scene where the other Friends characters catch her with Ross. "I loved that moment because when I appeared the entire audience went mad and they laughed for the longest time – until finally we all started to crack up."

"You can see me raise my scarf to my face because I was trying not to laugh. But it was just a great moment – a great reaction."

Wheeler also revealed that she didn't think a Friends reunion was likely.

"I think in many ways it'd be really great fun and a wonderful celebration...but It's unlikely to happen," she said.
