Having Issue With Left/Right Sidebar Height

I cannot figure out why on some pages the left and right sidebars will match up with the footer perfectly and on others there is a gap. For example. This (http://dunkingfrogs.com/?page_id=406) is the longest page on the entire website and both sidebars fill in the entire height of the page and lineup with the footer. Whereas, this page (http://dunkingfrogs.com/?page_id=332) does not fill in the entire height and has a gap at the bottom of both the left and right sidebar. Thanks in advance for any help.
