Last week I had to unclog a pipe under my sink. I feel the need to disclaim that I am no plumber, and I certainly don’t have the brand, make, and model of my sink memorized. For that matter, I don’t care for puzzles, and I am easily frustrated by an immovable object. I often compare my DIY skills to those of the three stooges. So, after opening my under-sink cabinet, the first thing that I did was break out the good old iPhone and open the YouTube app.
