It doesn't seem very fridge-ey to me. Maybe we could argue that it's an expression of doubt which arose after consuming some media (whatever article or blog post depicts the bear, I suppose), but it doesn't come across in the quote itself. I feel that a quote which best captures the essence of Fridge Logic (or Fridge Anything) should indicate the passage of time between reading/seeing/hearing whatever and then feeling the doubt. If anything, it feels like it's just...remarking on a coincidence and doubting that it could happen?
I'd say the same about the Futurama and Castle quotes as well.
