[jQuery] How do I completely overwrite an event?

[jQuery] How do I completely overwrite an event?


It seems that jquery is "appending" new events to any existing event
handler. eg:
$('##BLAH').click(function(){window.status+='a';});
$('##BLAH').click(function(){window.status+='b';});
Clicking 'BLAH' you get 'ab' on the status bar instead of 'a'??
