Ok, hows this: take the title of a film or novel, say for example Jaws, Hard Times or Bad Boys and do a caption based around it.
Now, you can interpret the title any way you like. Serenity could feature a tough, cigar chomping, stressed out businessman changing into a cool, blonde yoga teacher while The Cider House Rules could see 3 young drunks changing into bar wenches in a Cornish pub.
Thoughts? Feelings?
