John, I agree with you on all points, and I know this is unimportant in the larger scheme and I apologize for the anal retentiveness in advance, but...
It's "I couldn't care less." Not "could." I know most people say "could" but... "irregardless" of what most people say, it's still wrong. "Could care less" implies that you at least care a little, possibly even a lot. "Could not" makes it clear that you don't care at all.
I hate myself for this comment. But there it is.
