I remember back in my crazy days I had a 72 Fury 4 dr. Rear window needed replacement so me and my very drunken buddy decided we would replace it ourselves. Well after getting it in and losing or breaking a lot of the clips we decided to just silicone it in. Bad idea... Next day I was heading to work with a massive hangover and decided to open the drivers and passengers windows for air and Im driving along and I hear a woosh sound. Looked in the center rear view mirror to see the result of the window smashing into a million little pcs. on the highway. No one behind me thank God, I just continued on to work.
