While building Sierra Lodge, a particular brother was given the task of cutting rectangular holes into the floor so that we can have heater vents on the floor. Tim Fitz came back to find this hole as pictured.
Note the fact that the hole is not parallel to the wall, and the fact that they used a piece of plywood to try to make the HVAC metal boot fit into the trapezoidal hole. Tim looked at this hole and sarcastically said, "Umm... you know that you're supposed to cut straight lines, right?"
To which, the unnamed brother replied, "Oh, really?"
