Robert Florence sits on his sofa alongside his comedy writing partner of 20 years Iain Connell and, as you might expect, they begin with a series of voice impersonations.

"Do we sound exactly the same?" Robert asks. "Do you want me to speak in a high-pitched voice?" he laughs, raising his voice to a squeak.

Having worked together as writers on Chewin' the Fat and on their own show Burnistoun, the pair are once again preparing to work together, this time as they join the ranks of the Glasgow International Comedy Festival with their new show Uncles.

We caught up with them for a wee natter ahead of the show.

What can people expect from your new show Uncles?

Iain Connell: If you can imagine being at a family party and heading over to the corner and listening in on your two uncles putting the world to rights then that will be the world in which this show is in.

Robert Florence: It is just listening in on a couple of guys having a conversation about some daft stuff and some relationship stuff.

If you were Prime Minister for one day, what one thing would you change?

RF: Really the price of Space Raiders has to go back to normal. It's just no right, is it?

IC: I am thinking a certain amount of free pakora each day for every person, certainly late at night.

How far can you really throw a bottle of ginger?

IC: I threw it 17 metres and that's an empty one. If it's full, it goes a lot further than that.

Have you ever had trouble in a lift?

IC: I got stuck in a lift on Hogmanay one year in the Red Road flats and the lift was absolutely full.

RF: I just take the stairs. I like to keep my carbon footprint low and I think it's a terribly wasteful and irresponsible for people to use lifts.

Which of your sketches do people mention most?

RF: Younger guys, they seem to be into the Nae Rolls sketch a fair bit.

IC: For me, it is overwhelmingly wooden pallets. People send me photographs of pallets on Twitter and text message on a near daily basis since the sketch went out.

RF: I even send photos of wooden pallets to Iain sometimes.

If you could each pick two dream dinner guests, who would they be?

RF: I would take Joni Mitchell and Kate Bush to Stan's Chinese takeaway in Springburn and there's wee seats in there so we would eat our food then go and hang about up Springburn Park.

IC: I would take Billy Ray Cyrus and Miley Cyrus to a local takeaway and have a wee wander about, and I would get them to explain everything from the start. I want to know everything about that pair.

What most winds you up about one another?

IC: Robert's hat is quite annoying and he is sitting in his living room wearing it right now - you cannae look past the hat as far as I'm concerned.

RF: For me, definitely, the most annoying trait about Iain is the fact that he always brings fish for lunch up to my hoose. Today, for example, he brought a packet of salmon, which is obscene behaviour.

Robert, I saw you are hoping to do an alternative Scottish Eurovision commentary - is this still on the cards?

RF: I want to do that aye. Basically, my whole career is built on me hinting.

IC: Have you never noticed that Robert's Twitter account is just constantly full of announcements of things that never happen?

RF: Some of them do happen. My hip hop album has still to come but these things will all come in time. I am spinning a lot of plates here.

Who was the inspiration behind Jolly Boy John?

IC: I was sitting in the room and putting on voices and eventually I just went 'awrite' and I thought: Right, that's it, that 'awrite' is going to be the entire basis for a character. That one word.

What would you say was the game-changing moment for your careers?

RF: Getting to write for Chewin' the Fat, being a part of that writing team was a big step forward for us. It gave us a taste of working on a show that was very popular and let us hear people enjoying the sketches.

And then after that, it would be when we decided we better crack on with performing our own stuff before we were too old. When we decided to do that it was Burnistoun, obviously, so that was the next big moment.

What's your favourite character you have created and why?

RF: I enjoy daein the Quality Polis - it's good fun to dress up as the polis and eat loads of free pakora. So basically all my favourite characters and sketches are based around how much free food I can get to eat.

IC: Also, the chance to sit down during a sketch is good. So we like doing Peter and Scott because they are pretty much always on the couch.

RF: Aye, so we have questionable motivations when it comes to characters.

We know you are into gaming Robert but what about you Iain?

IC: I've got three sons and they are pretty much on the machines all the time so I will only get a wee shot at night. Robert the day, for example, is telling me he is excited he is going to play a game about farming. There's nae chance I am ever going to buy a game about farming. I just stick to the greatest hits.

What about you Robert, what's your favourite?

RF: Oh, that's a tough one, I would say probably Metal Gear Solid 3 was my favourite one but you know what, these things change all the time.

After Uncles, what are you both working on next?

RF: We are not thinking too far beyond Uncles. But you know us - we will probably have another big announcement.

You had a sell out run with Burnistoun Live in August, is that the last we'll see of the show?

RF: I still think there's plenty of stuff we can do with Burnistoun but right now we are just focusing on the next thing. It's like a football manager would say, we are focusing on the next match and will look no further than that.

Can you finish by summing up Uncles in three words?

RF: Loud, drunk guys... We should have called it that, loud drunk guys - that would have been good.
