Many people, including myself, have said at some point in exasperation: "I could care less" about such-and-such or so-and-so. But it's a strange expression, isn't it? Isn't the correct phrase "I couldn't care less?" "I could care less" is the opposite of "I couldn't care less."
I wonder if there are other examples out there, either where two opposite phrases mean the same thing, or where a phrase ostensibly means the opposite of what its author intends? If you think of any, feel free to comment here.
