Person A - man what a world, we've got adtech, cleantech, edtech, fashtech, fintech, foodtech, govtech, this tech, that tech, what's next?
Person B - Techtech!
Person A - what the hell's that?
Person B - well how about I give you a demo?
Person A - "backs away knowing what happened last time when Person B demo'ed the Smart Smart"
