I was helping my friend put a new gas tank on his truck, and was getting a bit too warm so I tossed my coat in the Tour. Force of habit, I locked the car before shutting the door. I locked my keys in my jacket inside the car. I never felt as stupid in my entire life. I just popped out the trunk lock with a hammer and a chissle. Sure I had a busted trunk lock, but really I didn't care since I was selling it a couple days later
