To enter the Caption Competition you need to create one or more speech bubbles, position them around the screen, and then fill them with humourous text. You can do all this using the handy flash interface below - click New Bubble to begin.

When you've finished, click Submit and your caption will be stored in our database. You can enter the competition as many times as you like.

We'll try and judge the competition every week or so - when we do we'll let you know in a news update on the front page.
