Annie is so cool and bobby pins open locks

Skyler came home today with an old-time bobby pin and said with awe "This can open any lock!" he thinks it's the coolest, and Annie, his class mate, gave it to him, so she's the coolest. He started pushing it into the locks around the house - I stopped him. He also said it can break rocks...?

Hope they are the next big detectives ala The Fringe and not the next Bonnie & Clyde :-)
