Tomorrow I've got a meeting at Broadcasting House to pitch some narrative comedy ideas for Radio 4, so today I've been putting some thought into exactly what I should present.

I find it's always a challenge to strike the right balance between, for instance, trying to come up with something really original, and making sure it's not so "out there" that no producer will be brave enough to touch it.

Also, when it comes to actually writing a script, as much as you want to make sure it reflects your own individual style, each channel has a distinctive tone so ultimately you've always got to make some concessions to that.

Anyway, here's a short taster of the three ideas I've decided to pitch to the BBC tomorrow morning:

Cell Mates

Cell Mates is an original sitcom set in the small, but recognisable world of homegrown terrorism.

Ahmed, Saeed and Fayez are firm friends and founding members of the world's stupidest and worst-organised Islamic extremist terror cell. Each week Cell Mates follows the exploits of these three amigos as they try their best to carry out atrocious acts of terror. Of course, through bad luck or — more usually — bad planning, their attempts always fail, often with hilarious results.

In the pilot episode, Ahmed phones in a terror threat but forgets to withhold his number, Saeed accidentally gives himself anthrax while planning a bio-attack, and Fayez learns the hard way that while No More Nails might be great for putting up shelves without a hammer, it's not a good substitute for the real thing in an improvised explosive device.

Alien Flatshare

"Modern life can be complicated, particularly when your friends are literally from another planet."

Alien Flatshare focuses on the lives and loves of six unlikely flatmates sharing a low-gravity, loft-style apartment on one of Jupiter's trendy outer moons.

In the pilot episode: Rooob thinks he's falling for MnyKKa and would love to surprise her with a kiss but doesn't know how to approach it because she has no discernable mouth parts; Jax-t and Tcho' have a big argument about keeping nitrogen in the flat — for Jax-t it's essential for life, but for Tcho' it's a deadly toxin; and all hell breaks loose when Qoomagh's cousins arrive unexpectedly and Mn Mn Mn accidentally eats them, thinking they are the exotic snacks she ordered from the local takeaway.

The Spearmint Badger

The Spearmint Badger is a half-hour sitcom about a dairy farmer on the brink of bankruptcy who decides that the only way out of his financial troubles is to open the country's first rural lap-dancing club.

In the pilot episode, The Spearmint Badger's big opening night is very nearly a complete disaster when the bus bringing in exotic dancers from Eastern Europe is stopped at immigration and Farmer Maguire is left with a club full of horny punters and no entertainment.

Just as things are about to turn nasty, the farmer's wife saves the day by putting on a special show of her own, while the farmer himself discovers a lucrative sideline by putting his milking machine to ingenious use in the back room, resulting in a stream of very satisfied customers.

I'm pretty confident the people at Radio Light Entertainment will go for at least one of these ideas, but you never know, so wish me luck.

I promise I'll let you know how I get on.
