Snakes On A Plane.
Let me just say that it is one of the most ridiculous and stupid movies I have ever seen in my life, but I thoroughly enjoyed it. It was a cheap laugh, and I still can't believe such a movie was even made. It reminds me of a conversation I could've had back in high school: "Haha, you know what would be a REALLY stupid idea for a movie? Someone tries to kill a guy by releasing a snake on a plane!" "Just one? How could you guarantee it would get the guy?" "Oh, well, a whole load of them!" "Hahaha, that'd be a stupid idea, you couldn't make a whole movie out of that. I'd laugh if someone actually made it!"
The fact this movie was made just cracks me up. I hope there's a sequel, Spiders On A Train.
