Thumbs up -- I do loves me some Fred. Seriously, wouldn't most of us love a girlfriend like Winifred Burkle? Smart, adorable, geeky... an ideal woman.
I usually think of her more as "cute" rather than "hot", but some of those pics... yowza! She can definitely be sexy when she wants to be.
I will admit that I too have always found her a tad too skinny, but, as others have said, it seems to be a natural skinniness, so I won't deduct any points.
