It started as an innocent Facebook post in the quiet town of Dripping Springs, Texas — population 4,200, and dropping fast now that everyone's attention is elsewhere. Cassidy Harlow, 24-year-old daughter of local plumbing legend Earl Harlow, posted a selfie in her dad's work shirt with the caption: "Grew up watching Daddy work. Trust me, I know my way around a pipe. 😉" Within 48 hours, the post had 2.3 million likes and approximately zero people were thinking about actual plumbing. Cassidy went from helping her dad fix water heaters to breaking the internet faster than you can say 'pressure valve.'
