1. Nip it in the butt vs. Nip it in the bud
Nip it in the bud refers to preventing the growth of a flower or plant. Therefore, this saying makes more sense using the word "bud" instead of "butt."
2. I could care less vs. I couldn't care less
Saying that you could care less implies that you do care at least a little. Usually, people mean they don't care about the topic at all. Therefore, I couldn't care less is more appropriate.
3. One in the same vs. One and the same
"One In the Same" doesn't really mean anything at all. Really the correct phrase, "one and the same," is the logical one because it means the two things are the same.
4. You've got another thing coming vs. You've got another think coming
This is an incorrect phrase that actually makes sense on its own. Therefore, it makes its own phrase. However, it is technically wrong. In order for the correct saying to make sense, it has to be paired with the other half of the saying, "If that is the way you think, you've got another think coming."
5. Each one worse than the next vs. Each one worse than the last
This doesn't make sense unless you can see the future, so the correct phrase is the most logical one.

You can do something on purpose, but not on accident
7. Statue of Limitations vs. Statute of Limitations
One letter does make a difference

9. Expresso vs. Espresso
Sometimes, our accents get in the way
10. For all intensive purposes vs. For all intents and purposes
The correct phrase means that all possibilities and circumstances are accounted for. Even though you might feel passionate and intense about your purposes, the phrase is wrong.
11. Hone in vs. Home in
The word "hone" means to sharpen and improve skills. To "home in" means to get closer to it.
