var badStuff = new Array("aaa","bbb","ccc","ddd","EEE");
var v = 'AAA hello world';
alert(badStuff.contains(v)); // should alert true because v contains aaa and aaa is in the baddStuff array
var v = 'This is a bbbbbbbb test';
alert(badStuff.contains(v)); // should alert true because v contains bbb and bbb is in the baddStuff array
var v = 'Hello World';
alert(badStuff.contains(v)); // should alert false
var v = 'CCC';
alert(badStuff.contains(v)); // should alert true
