in light of CA and GA's depositions, I think it is important to point out that the nanny in one tree hill matches the description of Casey's Zanny exactly in these ways:
25 years old
height 5' 7"
curly brown hair that has been straightened
brown eyes
straight white teeth
nanny is a "ten" (when exactly did Casey say this - her whole family quotes this fact)
matches closely:
weight 140 (hard to determine, really. some people have a hard time guessing other people's weight)
hispanic or, as Casey has said "mixed race"

Also - - interesting that the nanny gets choked in the end. IMO Casey likes this episode because someone else gets choked not Casey. Allegedly, Cindy choked Casey. I think Casey fantasized about making someone else the victim of a choking.
