Making fun of people

In a group email today the writer of the email mentioned that he needed to "get the download" on such and such a situation. Cracked me up. It reminded me of a site I found a while back with all the mistakes people make. For a long time I said "for all intensive purposes" instead of "intents and purposes," and I also had to make an effort to take up "just as soon" rather than "just assume." I wonder how many phrases I still have wrong. Funny.
