He's 40, recently married and has finally solved the Rubik's Cube. Dave Gorman is the man who presents his comedy very clearly.

The phrases “PowerPoint presentation” and “comedy gold” really shouldn’t go together.

Yet Dave Gorman has somehow managed to take a piece of equipment, which strikes dread into the hearts of office workers everywhere, and make it funny.

Perhaps it’s because he’s never experienced a PowerPoint presentation himself.

“I’ve never had to sit through John from head office telling me about sales figures from the third quarter,” admits Stafford-born Dave, who is touring the country with his PowerPoint projector.

“My act is very different to that. And it’s not a parody of a business presentation, it’s just a very handy way for me to quickly get a lot of information across on a big screen.

“I gather that one of the traditional rules is that you must never use more than 20 slides because that’s enough for the human brain to take in.

“I use 850 slides. It turns out our brains can cope with that many if they are funny and not about sales figures.

“One night, a Norwegian came up after the show and told me ‘You are the first person in this country I have seen who can use PowerPoint’.

“And after every show, the geekiest person in the audience will send me a pompous message on Twitter saying ‘You weren’t using PowerPoint, you were using Keynote!’.

“They accuse me of using different software because I am doing things that they can’t. Apparently I’m doing things that the experts don’t know how to do – well, me and the Norwegians.

“The funny thing is, I’ve never had any training. I just opened up the box and played with it.”

Dave, who dropped out of a maths degree to become a comedian, is a self-confessed geek. He admits he’s been whiling away the travelling time on tour by solving a 30-year-old mystery.

Well, solving it by cheating, to be exact.

He has finally completed the 3D conundrum of the Rubik’s Cube, still the world’s bestselling puzzle.

“I had one 30 years ago, when I was ten, and couldn’t do it,” he remembers.

“I got over it. But I recently picked one up and started playing with it, and suddenly it really annoyed me that I couldn’t solve it. I had to look up the answer, though, I don’t believe you if you say you worked it out yourself.

“Then I took it apart in a mathematical way so I could understand it. Yes, solving it has made me very happy.”

Dave has become famous for his wacky experiments, starting with Are You Dave Gorman? After a drunken bet with his flatmate Danny Wallace, he set out to find 53 people around the world who shared his name.
