Pop Quiz Clock Will Drive You Crazy (If You Suck At Math)

How well did you do in school? Well enough to read this trippy clock like it’s nothing? It’s pretty much one of the silliest (pointless?) things we’ve ever seen, but, hey, not all goofy tech stuff has to be 3G this, first-person shooter that, right?

The clock is actually called the Pop Quiz Clock, and is sold by Decor Craft, Inc. Instead of the typical clock face, you’re given quick little math problems to solve. So, -8=2-x equals 10, 50/2=100/x equals 4 and so on. Very dorm room-y, if you will.
The strange thing is that there’s no price listed, so we’ve no idea how much she costs.
We can think of no quicker way to annoy your friends. “Yo dude, what time is it?” Followed by a blank stare, and more than likely a few F-bombs thrown in your direction. Friendship!
