http://www.imdb.com/title/tt0073195/quotes
Quint: [seeing Hooper's equipment] What are you? Some kind of half-assed astronaut? [examining the shark cage]
Quint: Jesus H Christ, when I was a boy, every little squirt wanted to be a harpooner or a sword fisherman. What d'ya have there - a portable shower or a monkey cage?
Hooper: Anti-Shark cage.
Quint: Anti-shark cage. You go inside the cage?
[Hooper nods]
Quint: Cage goes in the water, you go in the water. Shark's in the water. Our shark.
[sings]
Quint: Farewell and adieu to you, fair Spanish ladies. Farewell and adieu, you ladies of Spain. For we've received orders for to sail back to Boston. And so nevermore shall we see you again.
