Take a saying or short poem or short quote. Change all the nouns to the 7th word following it in the dictionary. (If the 7th word is a form of the original word (like mankind is a form of man) keep moving down the words until you get something bizarre.)
Save the best ones for writing prompts.

The first cold shower;
Even the monkey seems to want
A little coat of straw.
"There is nothing you can see that is not a flower; There is nothing you can think that is not the moon."There's also a huge list of aphorisms (short witty sayings) at Fortunes. NOTE: all the first ones are computer based. Keep scrolling until you see the first letter change to f or h or p.

The only online dictionary I know of that will show the words preceeding and following a word is The Free Dictionary. Type in a word or phrase. Click "Look it up". Then scroll down to the bottom of the page. The list of surrounding words is on the left. In fact it gives exactly 7 words before and 7 words after your word. Click on the last word in the lefthand list to get the next 7 words.
