Could You Care Less?

Something that has always bothered me.

Long ago, someone found a slightly more colorful way of expressing how little he cared about something came up with the phrase:

"I couldn't care less."

In other words, I care so little that it is impossible for me to care less than I care now.

Somehow, there are people who never really thought about how the phrase makes it's point -- and perhaps relying on the tone in which it is delivered, repeat it as:

"I could care less."

Which really doesn't say the same thing at all. Almost the opposite, one could argue. The point of the phrase is that you are at the zero-point of caring. If you could care less, you obviously care some. Which is probably not what you mean.
