ooooo i had to do this for my philosophy class....
Pretty much the same thing that journalists do for news headings.
find a story you really like, and make a 6 word story out of it.
Like my favorite news story this year was the one where the kid forgot to take his meds got naked through a puppy at a gang of bikers and then excaped on a bulldozer.
in 6 word. man throws puppy at bikers naked.
Then you can make it more interesting
naked lunatic hurls puppy at bikers.
Anyway.... find a story you like. Summarize it into 6 words, then change the words to be the most interesting version you can.
Then google it to make sure you didnt rip someone off.
