LPL does funny videos every April 1st.
He has a company (Covert Instruments) that produces and markets a variety of tools associated with locksmithing and locksport.
I've been following him for several years now, and he's been a great source of information on locks and security devices. I started in what they call "Locksport" a few years back, figuring that it could be a handy skillset to have if/when SHTF.
