The shout became famous through SpongeBob SquarePants, where the My leg fish is repeatedly caught in slapstick accidents and cries out in distress. Clips of the line spread across YouTube, TikTok and soundboards as a quick reaction sound, often paired with falls, fails and gaming mishaps. Its short length and instantly recognisable panic keep it useful for creators who need a fast punchline, and it remains popular because the joke needs no setup or explanation.
