Alternatively, Peter could simply be one of my (I use the term loosely) multiple personalities. Note that we both showed up on the forums around the same time. Therefore, I may be the Easter Bunny in a different personality. However, this would require me to be aware of Peter as a multiple personality. In any case, I can confirm that Peter is not JohnK, therefore not Santa Claus, unless JohnK is another manifestation of my brain who simply discovered the forums earlier.

I am the Doctor, and THIS... is my SPOON!
