Ideas for new sitcoms.

Just base it around a group of lads lads. Have them go out drinking together. Shagging birds every so often. Farting on each other.

The possibilities are endless.

Myself and a friend at uni are trying to write our own sit-com, but it's actually pretty difficult to think what hasn't been done. We have the characters pretty sorted now, though, I think it has potential if we work hard on it.

"Cripes Jim, there's a black chap in your coal cellar!"
"How was I supposed to know that? I couldn't see him, could I?"
[raucous canned laughter]

As someone who's tried but never quite finished - it really is a bad idea to base a sitcom on something obvious, like "doctors", "teachers", "geeks" etc and just go from there, as more often than not the characters just end up as complete two-dimensional caricatures (see: The Big Bang Theory, The IT Crowd, etc). Focus on doing a decent, complex set of characters first, and if they're good enough, and if the stories are good enough, no-one'll care what they do. Seems you're mostly there...

I mean, Seinfeld? What the hell was that? Four people talking about nothing. For nine seasons. And bloody good it was (eventually).
