The Joker is a long-running villain from DC's Batman stories, famous for a laugh that sounds more threatening than funny. Short clips of that laugh have circulated online for years as ringtones, prank sounds and reaction audio, often stripped of their original scene so they work on their own. This phone-style version leans into that idea, sounding like a call from the character himself. It remains popular because the laugh is instantly recognisable and needs no explanation, making it an easy shorthand for chaos, mischief or a joke gone wrong.
