Dave Gorman (I)

The primary concept is one of baffling unreasonableness. Members of the public are encouraged to write in with their "wacky" suggestions for future inventions - basically rehashes of the "Letter Bocks" pages of Viz. If they are chosen, they then have to stand up and fill five minutes of prime-time television sparring with two professional comedians - who, additionally, have had time to prepare relevant material - in order to "win". As you would expect, it's a bloodbath - like a light entertainment Wounded Knee, but with a studio audience.

In the opening episode, Dave Gorman and Catherine Tate "challenged" four members of the public on their inventions, which included an anorak with an extra hood, for sharing with a friend, and some surrealist, sub-Vic Reeves nonsense about winning a race on stilts. As soon as Tate and Gorman started on them it was like watching two cats idly biting at frogs they'd found in the garden.

The BBC amazes me. It takes four years for Stewart Lee - a comedian with 17 years' experience - to get a six-part series; yet in Genius wholly inexperienced members of the public are expected to deliver five minutes of broadcast-quality improvised material at the drop of a hat. What, literally, is that all about?

The show may have had charm on radio but now it's transferred to the box with Dave Gorman hosting, you can obviously see the would-be genii and they just look mad.

Madder still, though, is the set designer who went to the trouble of creating the revolving stage complete with dry ice - and in the first edition, a model of a 100m running track to illustrate how lazy people would line up in running shoes 98.2 metres high and forward-flop over the finish line. Give me Sunday night telly over Friday post-pub bilge like this.

Making the jump to TV is this Radio 4 staple in which Dave Gorman and a celebrity guest consider 'genius' inventions from the public. Radio is probably the most logical home for the simple premise but this actually works quite well if you view it as some kind of idiot's version of Dragon's Den. In this series opener, Gorman and guest Catherine Tate consider a bus whose destination is decided on by public vote, and a man who wants 100m-high shoes for a very specific purpose.

Dave Gorman asks members of the public to write in with "inspired" ideas, which he and a celebrity guest examine in depth. Some of the best ideas don't even make it onto the shortlist. Cold-air ballooning ("all the fun of hot-air ballooning for people who are afraid of heights") was rejected out of hand, as was the suggestion that everything should be made out of leaves. But three equally crazed ideas make it onto the programme, and in each case the people who dreamt them up are subjected to a rigorous cross-examination. One of the ideas is for a bus service that operates on democratic principles, going where the majority of passengers tell it to go. Or there's the taxi driver who takes his passengers' shoes as surety. It's a harmless enough show and the aspiring geniuses are an entertaining lot, but it is little more than a pub game.

Not sure if this new show - despite the title - is genius. It's entertaining enough but it feels a bit wrong. Every week a celeb guest listens as loonies present a bizarre idea and then they judge whether it is genius or not. Host Dave Gorman is good though and this week's guest, Catherine Tate, gamely takes part. It's like a very silly Dragons' Den.

If you aren't familiar with the Radio 4 series, the best way of describing this format is Dragons' Den meets Room 101.

Members of the public pitch their ideas for useful inventions or innovations to the host Dave Gorman and a celebrity guest - tonight it's Catherine Tate - who then debate with increasing hilarity whether their idea is truly worthy of the label genius.

To give you some idea, the sort of brainwaves that got the thumbs-up on the radio in the past ranged from the eminently practical - selling socks in threes, rather than in pairs - to the surreal: running the House of Commons to the same rules as the panel show Just A Minute.

The advantage of TV, of course, is that we can see what prototypes of these ideas might look like and get some idea of how well - or not - they would work.

For instance, a bus whose journey gets decided by a democratic vote by the passengers sounds ludicrous enough on paper but, in practice, it's completely round the bend.

Comedian Dave Gorman hosts this quirky new series, which was first 'seen' on Radio 4. This is how it works - viewers submit bonkers ideas in the hope of being declared geniuses, and tonight, special guest Catherine Tate helps Dave consider - and sometimes road test - some of the revolutionary notions. They include a fully democratic bus with passenger steering wheels and cold-air balloons for those who hate heights. Brilliant stuff.

BBC2 attempts to fill the void left by the plundering of QI for BBC1 by bringing Radio 4's sort of comedy panel show, sort of not comedy panel show, to television. The ever likeable Dave Gorman invites members of the studio audience to pitch ideas for fantasy inventions, which a special guest each week will decide if it's 'genius' or not. It's all very lovely, but will it be a hardy enough format for the glare of television?

Dave Gorman: 'Being a twin is fun'

Dave Gorman, 38, moved from stand-up to TV with the show Are You Dave Gorman? in which he had to find people with the same name. His Radio 4 show, Genius, where suggestions for a better world are judged by Dave and a celebrity guest, transfers to BBC2 tomorrow night.

Dave Gorman: What makes a genius?

Genius. It's a much abused word these days - describe everyone and everything from Charles Darwin to round tea bags. But what exactly is it? And how easy is it to be one these days anyway? The comedian and film-maker Dave Gorman looks at two shining examples of genius to see if he could have thought of them first (if only it hadn't been for those pesky Babylonians)
