Writing the most important part of a sentence (at the end, between parentheses)

I've seen this writing style several times, where the most important part of a sentence - or a twist - is put at the end between parentheses. This is typically used in titles and gives the sentence an ironic or cynical tone.

Examples:

The new ways to lose weight (that don't work)

The car of your dreams exists (but you'll never have it)

A simple recipe for happiness (that nobody follows)

Does this writing style have a name? Which prominent author used it first, if any?

The rhetorical device of Paraprosdokian may be what you're looking for - it refers to a surprise or unexpected ending of a phrase or series.

*He was at his best when the going was good. (Alistair Cooke on the Duke of Windsor)
