Homer Simpson delivers a single sharp 'No!' in under a second, his voice flat, loud and instantly recognisable as a comic refusal. It feels abrupt, exasperated and funny, like a door slamming on a bad suggestion. The line comes from The Simpsons, where Homer's impatient denial has become a familiar cartoon reaction.
