I bought a pair of those when I was 16, for no other reason than I wanted them. Paid $21. Took em to school, dropped the key in the grass somehow, so my classmate Joe locked two of our friends to the fence. What a joker! Managed to pick one side open with a paper clip, but had to call poor Bill's sister to come get us and take us to my house to retrieve my spare key from the super-secret hidey-hole behind my wall calendar. Got scolded by the principal for that foolishness. Kept them for years, finally gave them to my brother the cop. Now I carry a key which I found near a dark stain on the floor of an empty 40' container I was sweeping out. The mind reels...
