Sharing the third spot are Mary-Kate and Ashley Olsen, "banking an estimated $15 million over the course of the year." At 22, the twins are nearly matronly compared to the kids who snap up their line of merchandise. The article notes that the twin sisters are "still best known for their shared role as precocious tot Michelle Tanner on ABC's Full House." That may change with the release of their coffee table book, titled Influence. Seriously, a coffee table book. I'm having a hard time even grasping that concept. What's next? A line of twin-themed coffee tables?

Zac Efron lands in the fifth spot with a respectable $5.8 million. That figure will no doubt climb even higher next year, with the big-screen arrival of High School Musical 3. Some of the other High School and Harry Potter stars round out the top ten, earning a whopping combined total of $107 million over the last year. Either tween consumers have way too much spending money these days, or these young actors have wizards for agents. Either way, it kinda makes you look back on your own teen years when you made minimum wage and cry just a little bit, doesn't it?
