To be strict, the source data was a red herring. A where clause shouldn't be based on the data you have, but the data you want.
In this case, for example, it doesn't matter that "Jim" exists in the source data (or "Tim" or "Kim" or "Bim" for that matter). What matters is that you want to retrieve only rows with "Tim" or "Kim".
If you used "Like '%im'", and "Jim" wasn't in the source data, your query would work. Once. But it would break as soon as someone added any other name like '%im'. If you get in the habit of using shortcuts rather than framing your query properly, you'll be rewriting queries more and more often.
Trust me, I know.
