Mickey Mouse is Disney's flagship cartoon character, created by Walt Disney and Ub Iwerks and debuting in the 1928 short Steamboat Willie. His high-pitched, cheerful voice, originally performed by Disney himself, became one of the most recognisable sounds in animation history. Like the signature laugh of Woody Woodpecker and the catchphrase of Pingu, friendly self-introductions in his voice have appeared across decades of cartoons and television. Online, the greeting circulates as a lighthearted meme sound, often used ironically to introduce something absurd or to open videos with a burst of childhood nostalgia.
