While in college... I came out of the dorm one morning to ride my bike to check the surf but my bike was gone. (it was locked to itself) I end up walking to the beach and see my bike locked in the back of an SUV. I was tempted to open the SUV myself using my master key (large rock) but instead I called the cops. They showed up at the same time as the owner of the SUV, I got my bike back, and he got taken in (there was another bike in there as well). Apparently he was so wasted he didn't even remember stealing the two bikes.
