Ed Byrne believes coming up with jokes is a bit like making compost.
The stand-up and familiar face on BBC Two's Mock The Week says sitting down at a computer to write his material doesn't do it for him.
He said: "That doesn't really work. I have ideas and then when I'm on stage I try and work them in.
"Sometimes it works and sometimes it doesn't, but it's a better way of working out what's funny then sitting with a computer screen trying to guess how big a pause to leave for a laugh.
"It's a bit like making compost really. You keep adding to the pile and eventually the manure turns to something useful."
Ed said Mock The Week was still a great TV show, despite the departure of Frankie Boyle and Russell Howard.
He said: "I just recorded an episode last night and it went very well. We all had a good time. Without the big personalities of Frankie and Russell you have more room to breathe. It's more relaxed on set.
"They didn't rule it with an iron rod or anything but it's just easier to get a word in. Everybody's a bit more equal standing now. I wish they'd get rid of the first round though, because it's very parlour-game."
Ed is performing a charity benefit to help the homeless, on July 18 at the Prince Edward Theatre in Soho, London.
