Can I make a Category Description appear at the top of a page of fetched posts?

I have a WordPress 1.5.2 blog with several different categories, such as Art, Music, Film, etc. I would like to set things up so that when a user clicks on a category in the sidebar, and WordPress thus fetches all the posts filed under that category, a brief introductory text for that category appears above the list of fetched posts.

In other words, let’s say a user clicks on “Film” in the sidebar. I’d like WordPress to display a short “static”
paragraph at the top of list of fetched posts, stating something like, “Here’s where I post my inane ramblings about the movies I’ve loved or hated, etc.” Under that paragraph, of course, is where I’d like the posts to be listed.

It would be great if this description/introduction could be culled directly from the “Category Description” field in the MySQL table containing all my categories. Is this possible?

Sorry if this sounds like a dumb question. I’ve looked through management-console and searched the support forum, and couldn’t find anything that directly addresses this concern. If you can help, thanks!
