Oh, God. It’s been five seconds since someone’s stuck something useless in my USB drive and I’m just exploding with technological tension at the mere thought of what might be shoved in there next. And here’s my answer: the scent drive. It uses the power of your computer to dispense smells. And like most things that get shoved in stuff, it’s a total let-down. If only they made smell emitter for your butt that ran on farts. Or a talking one for your mouth that ran on stupid. Then we’d be in business.
