Misheard expressions

Have you noticed how some common sayings that you hear but may not see as often in print as it is spoken, so it can be misinterpreted so easily?  I was just writing and Microsoft Word told me that "winfalls" was wrong.  I'm like, no it's not, winfalls, like when you win by getting something and it unexpectedly falls in your lap.  It has made sense to me for so long and it's close enough that most likely no one would correct me if I said it.  However, Word knows.  It gives me that red squiggly line that lets me know I am in error.  Windfalls works too, I suppose.  And I feel a bit silly that I didn't know it earlier.  I know there have been others but examples escape me at the moment.  Perhaps you have some examples.  What are sayings that you misheard for years?  I don't mean song lyrics, but rather common idioms or expressions that you should know, but find out that you've been a bit off.   I'm not the only one am I?  Just curious.

ok...i cant really think of any off the top of my head...i will post as i think of them... but the first thing that came to my mind was the fact that (more than once) i have seen the phrase "in and of itself" (which really means nothing at all, when you think about it)...written as "init of itself" which means even less. like does anyone consider what "INIT" could possibly mean?? ahh livejournals....

"For all intensive purposes" is actually "for all intents and purposes."

I believe that "init of itself" my actually be "in and of itself."

Things mutate when we say them too fast. I like mutations.

I recently saw an article which used the phrase "common-all-garden" instead of "common or garden".

I occasionally hear people say "I could care less", when they mean "I couldn't care less".

Here are a few...
"Wave of the future" vs. "Way of the future"

Holier than Though vs. "Holier than now"

I used to swear "might as well" was one word, "mineaswell".

P.S. Check out today's Huffington Post, even Arianna is blogging about apostrophes.
