While some comedians have a standard set that may evolve a little over the course of a tour, no two Ross Noble shows are ever the same.
English stand-up comedian and actor Noble is currently on tour with his new show Humournoid.
Renowned for his free-form, stream-of-consciousness delivery, Noble's gigs are heavily based around audience interaction.
"There's a bit of a fashion for people to write a show that's very much... That will have a bit of a theme," he told the Mercury.
"Some people will write out a show and just do that show for a whole tour, and then come up with another one.
"I work off the audience, and I'll improvise and play around with ideas and stuff like that.
"It's one of those things where the show is constantly changing, and it just depends on the night, depends what sort of mood I'm in.
"I try to stay in the moment as much as possible."
As a result, Noble said he will often go off on tangents, and not always remember to finish the story he was initially telling.
"That happens all the time, constantly," he said.
"But I think people have come to expect that when they come to see me."
Audience members can also be a helpful reminder if he gets sidetracked.
"At the end of the show, I'll say, 'are there any questions?' and someone will say, 'what about that thing you started telling us about two hours ago?' And I'll go, 'oh yeah, that's it'.
"What's brilliant about doing stand-up comedy is that it's probably the only art-form I can think of where basically you're the writer, director and performer all rolled into one."
Noble said stand-up has "exploded" in popularity since he started more than 25 years ago.
In the social media age, the public can easily voice disapproval and offence regarding jokes about supposedly taboo topics.
As a result, many high-profile comics have quickly back-tracked and apologised for controversial material amid public backlash.
"People on social media can complain about stuff, (but) nobody's really stopping you from saying anything you want," Noble said on the issue.
"That's down to the individual comic; what they want to say, and what they don't want to say.
"It's very complicated... A topic shouldn't be off-limits.
"It's how you deal with the topic.
"It's all about context. I think every joke has to be judged on its own merits. Who's telling it, and why are they telling it?"
