Friends star Maggie Wheeler reveals the funniest day ever on set

Maggie Wheeler spoke to Today Extra about starring on hit show Friends.

You don't have to be a diehard Friends fan to remember Maggie Wheeler - aka Chandler's irritatingly nasal on-off girlfriend Janice.

The 55-year-old shared plenty of memories with the core cast (David Schwimmer, Matthew Perry, Jennifer Aniston, Courteney Cox, Matt Le Blanc and Lisa Kudrow) across her 19 episode-run - but there's one in particular which stands out in her mind.

Wheeler told Today Extra hosts David Campbell and Sonia Kruger this morning that her funniest day onset was during filming for the scene where they all find out Janice slept with Chandler's best friend Ross.

The scene where everyone finds out Ross and Janice hooked up.

"Whenever I was on the show I had to make a secret entrance so it was a huge surprise for the audience," she revealed.

"I loved that moment [the scene where the Friends saw her with Ross] 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."

While Wheeler doesn't believe a reunion is very likely, she still loves the idea of getting the whole gang back together.

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

"I think we'll have to keep watching and imagining how this whole thing would be spun out if we had a chance to do it today."

Maggie Wheeler says she had to cover her face to keep from laughing.
