Main Idea: Display different random text show up every time a page is loaded.

NOTE: I had to put a space before all the tags ("< "), because otherwise blogspot would get all screwy in the editor - make sure to remove the spaces!

Implementation Details:
step 1 - place the random text
what this code does: define a < div> element on the webpage where you want the random text to show up.
Put this wherever you want the random text to go:

< div id="tagline">< /div>

step 2 - add necessary java code
what this code does: defines the different random texts in a javascript element, and the random selection function.
Modify the text strings to whatever you want them to say, and put this code somewhere in the < head> element:

    < script type="text/javascript" language="JavaScript">
    < !-- // TAGLINE CODE
        var taglines = new Array (
            "Random saying #1",
            "Random saying #2",
            "Random saying #3",
            "Random saying #4",
            // firefly quotes
            "You know, they tell ya to never hit a man with a closed fist - but it is, on occasion, hilarious.",
            "Also, I can kill you with my brain.",
            "I aim to misbehave.",
            "Well, my days of not taking you seriously are certainly coming to a middle." <-- notice no comma on the last line
        );
        
        function doRandomTagline()
        {
            var tagline = document.getElementById("tagline");
            if (tagline)
            {
                // get random #
                var rnd = Math.round (Math.random() * taglines.length);
                if (rnd == taglines.length) rnd--;
                // update doc
                tagline.innerHTML = taglines [rnd];
            }
        }
    // -->
    < /script>

step 3 - get the random text to appear when the page is loaded
what this code does: modifies the body element's onLoad property to run the randomizer.
Look for the < body> element somewhere right after the < /head> element, and change it to look like this:

< body onLoad="doRandomTagline();">

If you already have an onLoad method, declare a new init method that handles the current onLoad method, plus doRandomTagline(), then have the body onLoad call the new init method:

[...]
    < script type="text/javascript" language="JavaScript">
    < !-- // init
        function init()
        {
            doRandomTagline();
        }
    // -->
    < /script>
< /head>
< body onLoad="init();">

And viola, you've got random sayings. Now go annoy the heck out of people with them.
