The cliche goes like this: A picture's worth a thousand words. But most of the time, the best words are the funny ones you come up with yourself when you look at a picture. The images may not be intended to make you laugh, but a little creativity can go a long way.

Welcome to Caption Call, a new feature here at baltimoresun.com where you can share those caption quips with our Web readers.

Here's how it works: Each weekday, we'll post a new photo. Mull it over, come up with something clever and then use the handy "Post a Comment" function at the bottom of the post. Keep it humorous, but also keep it clean. Imagine that the people in the photo had a speech bubble over their head -- what would they be saying or thinking?

The most clever and humorous captions will be pulled out and reposted with your user name in our weekly recap. See, it's a chance for you to get a little bit of Web celebrity or at least compete with your friends.

If you need some inspiration, check out the "Most Recent Comments" section to the right and see if you can top them. The great experiment that is Caption Call won't work unless you contribute. Submit your captions no matter how silly you think they are -- that's the point!

Check out our first entry -- this picture of President Bush -- and keep the captions coming.
