Aside from cash, the most important thing that you should have with you at all times is protection. We're not talking about knives or brass knuckles for self defense (although those could also come in handy); rather, we're talking about good ol' latex because you don't want to miss out on a good lay just because you left home without one, do you?
Same goes for your data. Not that a condom can protect your files, but this condom flash drive will totally turn heads the moment you take it out of your wallet and plug it into your laptop. Just make sure you don't confuse it with the real thing because, you know, you'll hate yourself for it.
