Mega Shark Versus Giant Octopus 

Simultaneously the best and worst movie to ever be made. 90 minnuets of your life that you will never get back and you will not want back. It is exactly what it sounds like.

I just watched "Mega Shark Versus Giant Octopus." I don't even know what to say.

Bob: Just another of Megashaft's 'features' I guess! Like how you cant add another search engine in IE7 because you need IE7 installed first to do it :S
