Which one is which?

Hey, all you Airplane! heads out there. We've got a nerdy super-cut for you. Airplane! was released in 1980 and is widely thought of as just a general parody of disaster movie tropes. Actually, it's a pretty close rip-off of the 1957 film Zero Hour. Many of the lines are basically unchanged, but the delivery and responses make their meanings completely different. So, I guess the secret to creating classic parodies is having Leslie Nielson throw the word "lasagna" into a regular script every once in awhile.
