Do Everest fit windows?

Excuse me, could you clarify something for me? I came across a statement that said "Do Everest fit windows?" and I'm a bit confused. Is this a legitimate question, or is it perhaps a play on words? I'm not familiar with Everest being associated with window fittings, so I'm wondering if there's some context I'm missing. Could you please elaborate on what this might mean, or if it's just a joke of some sort? Thank you for your time.
