I found the answer to my own question. There are two plug-ins you can used to solve this:
1) Page Lists Plus
2) WordPress JQuery Dropdown Menu
This actually creates an entire new menu. For more info on this, visit, http://weeatbricks.com/2008/01/07/new-wordpress-plugin-for-creating-a-drop-down-navigation-menu-using-jquery/
3) This last option is not a plugin, but if you feel confident enough to tweak your php code, this page provides the code and instructions on how to alter the functions.php file that would enable you to have unclickable parent items in menus. The only thing is that the code works for drop down menus with three items or less. Here's the site: http://bavotasan.com/tutorials/how-to-remove-the-links-to-parent-pages-in-the-wordpress-page-list/
I assume that I never got an answer because nobody knew what it was. Well, I hope this helps those who've been wondering and frustrated.
