I remember playing a game called "Ad Lib" in my childhood; a seemingly regular text with words replaced by a blank, accompanied, usually, with the words' part of speech. After finding words that fit each blank's conditions, one ends up with a (usually) pretty funny text that is gramatically correct, but sounds totally wrong anyway.
Below is an example of an ad-lib-like form that can be created using the JavaScript file I've written; please try it out--simply fill in each text box, and then press "Ad Lib!" to see the result.
If you are interested in this ad lib idea, and would like to try customizing it, you can <<TODO: set up things so they are a bit more reusable, then complete this sentence...>>
If you come up with a good ad lib, please send me the file or a link. I'll be looking forward to seeing a good one...
