Everyone knows you can learn a lot on the internet, and some of it is even true. But if you want to know what's REALLY going on and important, then there's just one place to go: the computer club! Okay, so maybe it's not the club itself, but the three girls you're most likely to find there. And maybe they do spend more time chatting about their social lives and debating things like the virtues of ketchup versus mayonnaise than they do learning about the ins and outs of a keyboard, but whatever they're up to, it's sure to put a smile on your face.
