How do you delete apps off facebook?

To delete an application simply go to the application menu, (this might now be the bookmarks section of the page). You should see a list of all of the applications which you currently "use". Once there you can click the X next to the application name and it will ask you whether or not you really want to delete it. Once you contemplate this difficult question you can proceed to clicking "Yes" and be rid of whatever bothersome application you so choose.
