copy and paste from LO without classes

edit

When I copy and paste text from LO into an online WYSIWIG editor (like Tiny MCE), these classes and inline styles show up in my code, i.e.,

<p class="western" style="margin-bottom:0px;">Lorem ipsum</p>

How do I make it stop. I need to be able to copy and paste while retaining formatting like bold, italic, and hyperlinks, but there's no reason to have these classes/inline style appear.

Thanks.
