John Cleese as an airplane pilot captain--speaking on the plane intercom:

"Ladies and Gentlemen, There's no reason to panic. Please stay seated and enjoy your flight."

Few minutes later:

Cleese: "Ladies and Gentlemen, the airplane's wings are NOT on fire. Please remain seated."

"You know, it's times like these when I realize what a superhero I am." Tony Stark/Iron Man
