I had considered that as well. So it's either possible all the goblets contained identical material, a placebo, and the Sisters only planted a subconscious idea that the Doctor was in charge of his appearance because he was always in charge of it (as other Time Lords/Ladies have shown) or whatever it was then gave him…

That's all fine and lovely but the TARDIS supposedly translates to modern tongue? (Relative to that of the listener when it comes to the meaning of words)

In the "Night of the Doctor" mini episode, it was established the Doctor has/gets the ability to choose his face. He chose the 11th's face as well (young and handsome, to show off).

I also have to let the corn comment slide…
