Bottle spy

In the future when we have systems monitoring the statistics of our every action for our mere edification, there will inevitably be some numbers we just won't want to know. For instance, like how many times we got shot down at the party last night—or much the same, how many drinks it took to get to that point. But if you're the type who really must know how many tops you've popped, the BottleSpy will help you out by keeping accurate track of how badly you're roughing up that liver of yours. Ah, only in England. What, only 31 so far! Better get off the wagon and quick, lad!
