It’s long been known that humor can be the key to the success of any film, so it’s no surprise that the funniest movie lines of all time also come from some of the most successful films of all time. These are the films that fans will watch again and again, despite how old they are and share them with their friends and even their children. It’s these films that don’t age and whose humor remains just a potent as when the films were first released.
Jim: [consoling Bart] “What did you expect? “Welcome, sonny"? "Make yourself at home"? "Marry my daughter"? You've got to remember that these are just simple farmers. These are people of the land. The common clay of the new West. You know…morons.” (“Blazing Saddles”).
Like “Army of Darkness”, Monty Python’s take on the Arthurian legend is just filled with fantastic lines and is easily home to some of the funniest movie lines of all time. This one refers to an argument Arthur gets into with a peasant living in a commune who takes issue with the entire idea of divinely-appointed royalty and is not afraid to speak his mind.
Rumack: "Can you fly this plane, and land it?" Ted Striker: "Surely you can't be serious." Rumack: "I am serious…and don't call me Shirley." (“Airplane”).
Sure, Leslie Neilson had a great career prior to his appearance in this movie, but his deadpan humor is what he’ll be known for in the annals of Hollywood legends. “Airplane” simply would not have been the same film without him. In one of the funniest movie lines of all time, Nielson’s character Rumack is trying to explain to Striker (Robert Hayes) how grave their situation is now that the pilots are incapacitated and they need someone to fly their plane.
