About ten years ago I had a bookie who had a pet piranha. One time he opened his safe to get me some money and all that was in it was a single stack of hundreds, a gun, and a tiny black bag. I asked him what was in the bag... He opened it and poured out a bunch of loose diamonds on the table. I asked him why he had all these diamonds. “I bought them.” But why? “Because I thought a bunch of diamonds was a cool thing to have in a safe.”
