Even though you may feel like it, it’s usually not appropriate to wrap your arms around a plumber just because he repaired your toilet or fixed a leak, but on April 25, Hug A Plumber Day, it might just be acceptable.

National Today shares that plumbing started in in 2700BC in Pakistan and northwest India, and the first plumbers were probably not far behind. The career offers great benefits, because plumbers have to do things that most people refuse to do.

If your family needs a plumber on this day, or if one of your relatives actually is a plumber, be sure to offer them a big hug… but you may want to wait until they’ve cleaned up from their most recent job.
