@tuseroniJan 27.2011 — #var texts=["happy monday","i hate mondays","wee another monday"]//etc..
var now = new Date;
if(now.getDay()==1)
{
alert(text[parseInt(Math.random()*text.length)]);//doesnt have to be an alert
}
this will be a random message every time the page is loaded on a monday. if you want to message to be constant you may want to use a server side language or store it in a localsession/localstorage variable
