I think that we all have our own style of humour which comes to us naturally. Nearly all comedians, for example, have recognisable styles which they more or less stick to. (Deadpan stand-up, visual humour, quickfire gags etc.). Off the top of my head, the only exception I can think of is Rowan Atkinson. He made his name as a clever, verbose performer and later switched to the silent comedy of Mr. Bean---which I found extremely UNfunny, but that's just me.
When I first started writing Andy Capp, I tried hard to emulate Reg Smythe's style but soon found myself falling back into my usual, less-than-subtle ways.
Humour SHOULD come naturally---when it's contrived, it loses its edge.
