The new Seth Rogen/Zac Efron comedy Neighbors stunned Hollywood by grossing nearly $50 million its first week in theaters, completely clobbering the second week of The Amazing Spider-Man 2. Beyond the fact they timed the opening very well, the reason it made such a killing is extremely simple: It's really, really funny.
Now we have a question for you: What is the funniest movie of all time? Feel free to vote for an old-school favorite like Some Like It Hot, a modern-day classic like The Big Lebowski and Wet Hot American Summer or a slapstick masterpiece like Airplane! or Naked Gun. Pick whichever funny movie you want, but please only vote once and only for a single movie.
