Like to cellophane the toilet seat and put sugar in the salt shaker? If tricking people is what you do, then you\'re going to love these unisex specs from iChoose. The chunky black square frames look sensible enough. Not too big and not too small, with curves in all the right places. But here\'s the fun bit. These glasses come with three sets of arms, meaning they can switch places more often than The Parent Trap twins. And the best bit is they\'re super subtle, so people won\'t have a clue. Black, burgundy and brown zebra print; just different enough to have people guessing. Go on, mess with their minds. You know you want to.
