Here’s a site that puts LOL cats to shame.

Hahahorses puts laughter to good use. Every day they post a new photo and invite readers to submit a caption. Readers vote for their favorite captions and the caption with the most votes wins.

But laughter in this case is good medicine for horses as well as people. According to their website, Hahahorses.com donates either all or a portion of its revenues (the copy is different on different pages) to horse related charities.
