That sounds familiar. My son Nick was trying to show his brother how to pick a lock on one of our cars, he knew how to do it because he saw it on TV. suffice it to say that we no longer can unlock the passenger side door on our Saturn from the outside. Of course he was 11 years old at the time so he can be excused somewhat. The upside to this is that now that he's 15, we get the disgusted eye roll and loud defensive retort every time we bring it up, so at least it has ongoing entertainment value.
