Ya know, I did find something very valuable whilst riding my motorbike on the most recent run to the drug store:
I was wearing (in addition to other clothes) a pair of somewhat-baggy khaki pants (my standard uniform, as it were) and as I went over a sealed crack in the pavement I heard something go "fwap".
Now, most people will tell you that I am the most curious person they've met. Actually, no they won't. That's just what the polite people will say. Many will use the most common euphemism for "rectum". Either way, I just HAD to see what made that sound. HAD to. It didn't seem to be anything necessary to the function of the bike. So back I went. And there, in the street, was my WALLET! Aaaaaaa!
Okay, so I spend a lot of time being broke, but I had money that day so that made it valuable.
