How to change a css class with using jQuery and a .click function

Hi jQuery Forum,
 
First off , you and I have something in common...
 
we like to learn new technologies...
 
it makes life different and fun and it feels new...
 
 
 
My Q is about a doc that I have.
 
I have assigned a css class to an anchor or link...in the .css file.
 
I am looking to make this link change its css style from the orignial to a new css style.
 
I must be rusty because ... I attempted to use .addclass ... to the link...
 
 
Now ... I am an unlucky guy whom sometimes finds things are bugged or broken or whatever...
 
so that is my luck...
 
 
So two things I see affecting my problem is ....
 
one) I have assigned a style to the "a:hover" selector and the a:link selector I put it as blank    a:link { }
 
one.five) I don't know if these are permanent and unchangeable due to useability of anchors
 
two) I have assigned two styles to the link and the doc has links being used elsewhere on the page ...
 
two.five) i dont know if this will be conflicting in the doc tree
 
here is my codes:
 
.yesbaby{
 display:inline-block;
 border:4px solid #333333;
 background-color:#999999;
 color:#0000FF;



 text-outline:none;
 text-decoration:none;
  
 font-style:normal;
 font-size:16px;
 font-family:"Comic Sans MS", sans-serif;
 font-weight:900;
 
 border-top-style:solid;
 border-right-style:solid;
 border-bottom-style:solid;
 border-left-style:solid;
 
 border-top-color:#333333;
 border-right-color:#333333;
 border-bottom-color:#333333;
 border-left-color:#333333;
 
 margin-top:0px;
 margin-right:0px;
 margin-bottom:3px;
 margin-left:0px;
 
 padding-top:3px;
 padding-right:3px;























 padding-bottom:3px;
 padding-left:3px;
}

 
.yesbaby2{border:4px solid #333333;background-color:#333333;color:#66FF00;text-decoration:underline;}
here is my jQuery:
 
 $(document).ready(function() {
  $('p').hide(); 
   $('a.timetoread2').click(function() {
    $('p').show();


     $('a.yesbaby').addclass('yesbaby2');}
     $('this').hide();
      return false;
   });


 });
 
 
If I wrote too much... sorry, there is nobody here to talk to today...
 
here is my html:
<a class="yesbaby timetoread2" href="#">Decide to read</a>
 
 
In the end... the link makes my paragraph show
and
I want the link to change its css style...
from
yesbaby
to
yesbaby2
