At the house we're renting, there is a hookup spot for our washer and dryer. My washer has a drainage tube that is mostly flexible, but there is a long straight part at the end. Where the pipe is to insert the drainage tube, there is a shelf above it that is too close to allow you to fit the straight part into the pipe.
So I got a saw and made one diagonal cut, then a second cut from above to make a little notch in the pipe, giving us enough room to fit in the drainage tube. I totally fixed it in one try, despite my wife's doubts in my ability to do it. I'm currently feeling very manly.
