You sure made me feel better for all the dumb **** I usually do to myself!
When I was a teenager living with my mom, I bought a 73 Dart sport and I was working on it in the garage. Set the E brake, worked on the front brakes. Without thinking I lifted the rear to do the rear brakes, as soon as both tires were off the ground the car rolled back and pinned me to the garage door.
Luckily it was level ground, and I’m a Neanderthal, I was able to push the car forward. Dented the **** out of the garage door and learned a valuable lesson about wheel chocks.
