When One Line Was Enough To Make Everyone Join In
Long before memes and viral TikToks, television had catchphrases. Some were funny, some were heartfelt, and some became so popular that people repeated them absolutely everywhere. They showed up at school, around the dinner table, at the office, and in everyday conversations until even the biggest fans were ready to hear something else. Love them or hate them, these lines became unforgettable parts of TV history.
