December's Challenge - Remove a Sock

The challenge for December, 2012 is here!

You will teach your dog to. . . remove a sock from your foot (well, anybody's foot. . . it doesn't have to be yours.)

The rules for the challenge:

1.  The final behavior is the dog removing a sock from a foot. You are allowed to have about an inch of sock hanging loose off your toes if you wish. Otherwise, the sock must be in the normal position on the foot. 
2. Your video should include some of your training sessions and the final product. Your video should be posted to youtube, photobucket, or any other video sharing website, with the link put in the comments for this challenge. 
3. Your video will be graded on: 
1. Timing of your mark/clicker. 
2. Placement and use of rewards to facilitate behavior. 
3. Your training journey (how you got from Point A to Point B). 
4. Creativity shown by your dog. 
5. Putting a link for the video in the comments of this post by the due date. 
4. Bonus points will be given for: 
1.  Showing sock removal from different feet. 
2. Letting us hear a squeal or groan of pain when your dog gets the foot rather than the sock. (Yes, I'm evil.) 
3. Training bloopers! 
5. Videos are due by December 20! Update:  Challenge extended to January 20!

Ready, set, go!
