Home Improvement ran on ABC from 1991 to 1999, starring Tim Allen as Tim Taylor, host of the fictional Tool Time show. His grunt became the character's trademark, used instead of words to show confusion, excitement or approval. Clips of the sound spread online through soundboards and meme edits in the 2000s, where it became shorthand for stereotypical dad energy and overconfident DIY. It remains popular because the noise is instantly recognisable even without the video, and works for any situation involving tools, repairs or baffled reactions.
