Welcome to the Fantastical Fifty* (you could also make other use of the FF and rename its slave the Faffing Fool (that would be me).
Sometime last month I read this interview with Kelly Link and in it she suggested the following story generating idea (via Stephen Dobyns). In an hour (or more - I took about two) write down 50 first sentences, the first things that come out of that delightful noggin of yours (I have a book of keywords and weaved my sentences around the first 50 words I stumbled across). Then pick 25 of those sentences and write 25 first paragraphs, and out of those you should be able to conjure up half a dozen short stories.
Now, I'm a greedy gal and I'm currently trying to weave 50 stories out of 50 first sentences (because they are all undeniably...partway to...almost...well I thought they were wonderful for at least 50 minutes). I do expect the number to drop by at least half before the year is out, but at the moment I'm having fun and it feels like a weird mix of procrastinating and writing at the same time.
*This is what happens when you realise you have almost no stories 'out there'.
