I hear the latter holds more water. I agree.
If your characters are solid, and their dialogue distinguishable (basically they have their own personality) then you can pull off comedy without one-liners, in my opinion.
Personally I loathe the idea of having canned laughter on a show I wrote, because I think it's a con to make your audience laugh at what is otherwise not very funny. Amusing, maybe, but not laugh-out-loud funny.
EXAMPLE:
INT. FLORISTS - DAY
It's raining outside. A SWEET OLD LADY enters holding a motorbike helmet.
TONY is a florist and he's arranging some flowers in a vase fairly heavy-handedly. Some of the flowers are breaking under the strain and petals are falling all over the desk.
OLD LADY
Hello. Have you got any Lillies?
TONY
(Still focused on the flower arranging)
No.
OLD LADY
Well, have you got any roses? It's
for my husband's funeral you see.
TONY
No Roses. Got Daisies.
OLD LADY
Is that all you've got? I was planning
on spending a bit more on him you see.
TONY
Got daisies and that's it.
OLD LADY
Are you alright? You seem a bit upset.
TONY
(Stops arranging and looks at her)
I don't know the first thing about
flowers. I know we've got daisies.
They're over there.
He points to a pot of decomposing daisies.
OLD LADY
OK I'll take a dozen.
TONY stops what he's doing and gets the daisies. Puts them in a piece of Newspaper.
TONY
Open or wrapped?
OLD LADY
Oh, wrapped please.
TONY
Salt and vinegar?
God that was shit! But just an example of character exposition. Here's the one-liner version...
INT. FLORISTS - DAY
It's raining outside. A SWEET OLD LADY enters holding a motorbike helmet.
TONY is a florist and he's arranging some flowers in a vase fairly heavy-handedly. Some of the flowers are breaking under the strain and petals are falling all over the desk.
OLD LADY
Excuse me, have you got any Lillies?
TONY
Do I look like a bloody florist?
OLD LADY
It's just I wanted some flowers
for my husband's funeral. He had
dissentary.
TONY
Shit happens.
OLD LADY
That wasn't very nice.
TONY
Neither is Syphillis dear. Trust me.
You want some or not?
OLD LADY
Go on then.
TONY Nods.
TONY
You... erm... wanna go out back?
OLD LADY
Where shall I put my helmet?
TONY
Anywhere you like love. Where
shall I put mine?
Even though both are worth a laugh, I think one liners hinder dramatic tension which I think is an important aspect of a comic scene.
Feel free to discuss and rip apart my shitty examples!
