It's easy to join in! All you do is post your best (or worst!) caption to my photo below, and then click the link underneath to take you to the other entries :)
Oh, and apologies to those of you who wanted to leave a caption last time and couldn't!! I had "G+ Comments" enabled before realising that unless you have a G+ account you couldn't leave a blog comment. D'oh... All sorted now though, xxx
