How do you put your processor in?

How do you put your processor in? I know there is the one proven way to do it with the water band. I know many people ignore the basic procedure to putting in processors. I learned the quick way my first time into it. I put it in while sitting on my bedroom floor. Did I mention my room is carpeted. Enough said. Laugh as much as you want for the fact I had to run and get a second processor.
