Lock Picking is actually a really classic nerdy hobby. I think we almost did an episode on it once, but we didn't know enough to talk for 20+ minutes. I think it deserves a thread here.
Anyway, I thought of this because I was considering going to the public pool near my house today. Apparently the lockers are free, but you need to bring a lock, which I do not currently own. The hardware store was closed, so no pool today. Like you do, I go to buy a lock on Amazon.
Challenge: Find a reasonable combination or key lock on Amazon for which there is no video on Youtube demonstrating how to easily open it.
