Stupidest thing you\'ve ever done while workin on your Blazer? Well this was funny as hell. I went over to my buds house to change my u-joints and his brake pads. The night before I hadnt gotten any sleep at all so I had to go do this sh:t all wired out. Anyways he told me to chalk the tires. His kids had some sidewalk chalk laying around in the garage. I grabbed a piece and handed it to him and said here you go. That is about the stupidest thing I have ever done. I could'nt belive I did it myself. What about you?
