But now for the official stuff: this contest is only open to US residents of age 13 and up. I'm very sorry if this excludes you, but legal restrictions make it very difficult for us to run a more inclusive contest. (We can run this type of contest and include some of our readers, or not run contests and include none of our readers.) Before you enter your caption, you'll want to read through the official rules.
Legal business concluded, what are you waiting for? Get to captioning!
