Checkbox shows hidden field - not working onload

Question

I am using this probably ugly javascript to show a text box (in a li tag plus its label) if a checkbox is checked.

   $(\"#li-2-21\").css(\"display\",\"none\");

Extract your click function into a separate function (not inline) and run it on the load of the page:

function ToggleCheckbox() {
    if ($("#Languages-spoken-and-understood-8").is(":checked"))
    {
        $("#li-2-21").show("fast");
    }
    else
    {     
        $("#li-2-21").hide("fast");
    }
}

$(function() {
    $("#Languages-spoken-and-understood-8").click(ToggleCheckbox);
    ToggleCheckBox(); 
});

If you want to clean it up a bit I'd extract the checkbox and languages element into separate vars:

var languages = $("#Languages-spoken-and-understood-8");
var checkbox = $("#li-2-21");

make sure you place them in the appropriate scope though. This will mean that jQuery doesn't need to keep requerying the DOM to find them.
