The Lee & Herring comedy duo was responsible for the Fist of Fun radio and TV series - which was recently released on DVD - and its follow-up This Morning With Richard not Judy.
> Richard Herring launches short film contest: 'I want to be surprised'
Lee previously said that the pair could play a gig together to mark the DVD release. However, he later suggested that an eventual reunion will only get funnier the longer they leave it.
"Stew did mention it to me a couple of months ago and I said, 'We'd have to do it in January or February', and he didn't reply!" Herring told Digital Spy.
"I'm on tour, we're both very busy! Again, I'm very proud of the fact that we've brought out these DVDs, and Go Faster Stripe did an amazing job with them.
"It was very nice to get a mention in the BFI roundup of the year top DVDs amongst all these artistic films."
Herring added: "I think it would be good if we could find time to do a gig for it, but I don't know whether we will and what we'll do exactly if we do that, I don't know.
"There's no immediate plans, I'm afraid. I think if we do get back together it'll be about 20 or 30 years' time, and we'll be really old, and it'll be really funny to see two old men farting about."
The pair this year reunited on stage - for a discussion rather than a performance - for an episode of Herring's Leicester Square Comedy Podcast.
Herring has cast doubt on being able to release This Morning With Richard Not Judy in full, and said that a 'best-of' disc may be an alternative.
Asked if he would ever give his mid-'90s play Punk's Not Dead a revival, Herring said: "There's always a chance - there's a couple of things I'm working on now that are ideas from the '90s that I'm having another crack at.
"I think it's being done as an amateur production somewhere. It's one of those things that might come up again.
"It was quite topical of its time, but I think that's not necessarily a bad thing. I'd love to get back into writing some plays. They never really got any kind of recognition.
"I think that Punk's Not Dead was the tightest possibly. I don't think it's the best of all the plays, but I think it's among the most commercial... I'm very proud of that play particularly.
"When I read it again it does emote a little bit with me, and I kind of like it. I think all theses things are a journey towards something else maybe, I'll hopefully get the chance to write more drama."
