I have another question - which probable has been asked before..

When Riddle was talking to Harry in the CoS, Riddle mentioned that
Dumbledore during his time at Hogwarts taught transfiguration.
McGonagall transforms into a cat, and I was wondering if Dumbledore
transforms into anything?  I suppose you don't need to in order to
teach the subject....just curious if anyone had any thoughts on the
matter.
