Surely you can’t be serious: An oral history of Airplane!

AV Club:

In 1980, a trio of gentlemen from Wisconsin – Jim Abrahams and brothers David and Jerry Zucker – took a cast of predominantly non-comedic actors, put a parodic spin on the disaster-film genre, and created a film which not only made moviegoers howl with laughter but also earned critical acclaim.

While it may not be the greatest movie ever made, it probably ranks in the top five of the silliest movies ever made. I loved it as a kid and love it even more as adult. Every time you watch it, you see and hear more gags and funny bits. To this day, if I ever hear someone say, “Surely, you can’t be…” I immediately flashback to the line in the movie.
