Time to vote!

Tanner has such old man knees, and Jane has such old woman knees. We can't get enough of those wrinkles. But whose knees are whose? Check out the poll to the right to cast your ballot.

ETA: Poll closed! The majority was correct: Jane is on the left, Tanner on the right. Jane's skin is pretty pink and Tanner's is more yellow, so that's a dead giveaway for those in the know. And Tanner's a bit beefier, too, if I can call my five-pounds-at-birth son "beefy." Thanks to those who voted!
