This is the first time, I actually use a well known person for a manip or story, but I rediscovered this picture and just had to use the potential. 
Quickstory: After one of her shows Lindsey Stirling and two of her dancers sit down backstage to have some magical fun. All three had been dacing barefoot during the show and so their soles had become incredibly dirty. Lindsey now took her magical bow, which only she could wield and began.
In the following hours they manipulated their bare feet, arms and noses in many different ways. Exchanged and cloned feet and many more things.
If you can tell me all manipulations, you will get....NOTHING, sry. XD
