Fellow net nerds, help me please!!!

I want write a book about terrible movies. I'm talking movies that warrant actual genuine serious consideration of that old chestnut, "What the *beep* were they thinking?!!!" Like, real amateur crap. And that's where I need your help.

What is the worst movie of all time to you? If you would like to elaborate why and what this film means to you, go for it. If you have an anecdote to go along with it (first time seeing it, seeing it at a midnight screening, etc.) that's terrific. I want to hear what you have to say. I'm looking for 100 titles.

Basically, this book will be written to you, the internet crowd. Because you're the ones who introduced Shark Attack 3: Megalodon to the world. You're the ones who bumped Snakes on a Plane up to an R-rating, and assisted in increasing its already overflowing camp value. And you are the ones who revel most in the skewering of obscure subject matter.
