Heh! The Colonel! Honestly, I don't really resonate with any of the characters mentioned, although I appreciate them all. Lately I've felt like more of a Trapper John (from the movie version, which I really love) if I had to pick. And at least no one called me Frank Burns.

Unless, of course, you mean the OTHER Potter in which case I'll be an Aquarius (he has to be) and step into James's shoes for a little bit.
