This problem has plagued me occasionally, and I'm finally asking: What is the proper grammar (specifically, verb use and capitalization) in the following pun situation?
The only Windows I want to hear about is the operating system.
It's being used in a written place. If I am, in fact, referring to the OS, I should capitalize Windows, but I don't necessarily want to give away the joke at the very beginning of the sentence; additionally, I don't know whether I should use "is" (which would be correct for the OS), or "are" (which would be correct for multiple glass surfaces out of which a person can look).
I realize it's a fairly absurd situation, but I still want to do it correctly.
