The phrase "It is what it is" bugs me. It falls into the category that includes phrases/clauses like "Going forward..." (as if you could go backward) or "To be honest" (an admission that what you're about to say is a departure from the norm).
I just heard a new one in the concierge lounge at a Marriott: "It'll be what it'll be". I think it was related to sports.
So, here are some suggested enhancements to the dialect:
* It won't be what it won't be
* It will never be what it never could become
* What wasn't, wasn't
* To be or to be, that is the [rhetorical] question
* It probably wasn't meant to be because it wasn't meant to be
I'm sure there are more clever opportunities here.
