Between Sarah's iconic one-liners and everyone knowing a mam like Mary, there is no shortage of laughs when they come on our screens.
Writer and creator Lisa McGee has announced that fans will be able to learn more about the lives of teenage Mary and Sarah in a special flashback episode.

According to Digital Spy, she wanted to pay tribute to the strong mother figures in the series with an episode dedicated to them.
Episode 5, called 'The Reunion' will take us back to the 70s when the pair were a similar age to their children in the current timeline.
"Writing this show, honestly – and this might sound a bit sentimental – it's been a real learning experience for me as a person, not just a writer,
"I don't talk about a lot of the terrible things," Lisa told Digital Spy.
"In Northern Ireland, you handle it with humour and you just crack on. I think for the parents' generation, it was a war zone. It was horrific what they went through, and we just didn't appreciate it.
"We just moaned and then complained when we were not allowed to do anything. By writing the show and looking back I realised why they were so strict, why the school was so strict, what they had seen, what they lived through, and I have such an appreciation and respect. I'm so embarrassed at how we behaved now!
"They were incredible what they got through, they're just the strongest people, that generation."
She continued: "There was hardly any jobs for men, and it was the factory town, so people earning the wage and you know, head of the household, it was mummy culture. I just want to just sort of pay tribute to that, and to the women that got us through it.
"The third season, it's my last chance, I have to do it now. So that was the first episode of this series I pitched to Channel 4. It's risky because it's very different, and it's not the show's formula, but they just went 'Yeah, go for it' because they're Channel 4 and they're incredible and taking risks is the thing they're known for."
Derry Girls continues on Tuesday at 9.15pm on Channel 4
