How about having a thread where aspiring strip writers can put forward story-line ideas, and experts like Roger, can say why they would or wouldn't work?
Here's one I've just thought up:
Bloke (in flat cap) leaning on a pub bar, says to barman: "And then I said "If that's your attitude, I'm never drinking here again".
Another guy walks in saying "Hey, Arny - any idea why the landlord of your usual boozer's throwing an impromptu party?"
Would that work, and if not, what's not quite right?
