I'm at that age where if you flattened out all the wrinkles I'd be seven feet tall.

Orben’s joke turns aging into a visual, physical exaggeration: wrinkles become so numerous that, if “ironed out,” they would add comical height. The humor relies on hyperbole and a mock-scientific premise, a hallmark of mid-to-late 20th-century American one-liner comedy. Beneath the gag is a familiar, self-deprecating acceptance of getting older—acknowledging bodily change while reclaiming it as material for wit. The line also plays on cultural anxieties about appearance by converting them into an absurd “benefit” (being taller), suggesting that laughter can be a way to domesticate the indignities of time.
