"Narrator: From her beginnings on a Navy drawing board, through the months of secret field experiments out on the Western desert, then through the desperate search for new metals with the properties she needed, she was designed to be the nation's greatest weapon of the seas - the atom-powered submarine. Her engines were to be a miracle of speed and power, her sides strong enough to withstand any blow, her armament and fire power of greater force than the worst enemy she might encounter. The mind of man had thought of everything - except that which was beyond his comprehension!"

"Do you mind if I make a mental comment upon the nature of women?"

"The next time I cruise in these waters I'm going to have torpedoes with warheads on them."

"This is a submarine, John. If it can go underwater, it can go under ships, too. This is a deep channel. Better run below if you don't wanna get wet."

"Captain Jack: Attention all hands. This is your captain speaking. We're getting more reports of this half shark, half octopus creature that's terrorizing the coast, but please don't panic. There is a way we can stop this thing. Virgin sacrifices. Yes, the Mexican Fish and Game Commission assures me the only way to appease this beast is to offer it a beautiful virgin, preferably 18 to 25 years old. I repeat - Sharktopus wants our virgins."

"What was the unspeakable secret of the sea?"

"This Gangster's "Single Partner" Isn't Even Human!"

"So I got the girl... and guess who got the gold."

"I had to go the Santo Domingo bar and I had to find Agent XK-120, whom I'd never met."

"Mary-Belle Monahan, alias Mary-Monahan Belle, alias Belle-Mary Monahan, alias Monahan Marybelle: they say she was a gun moll just because Lucky Luciano gave her a Rolls Royce every Christmas and they can't really prove she sneaked into the Hollywood Bowl with a tommygun and rubbed out the convention of police chiefs in 1956. Oh, I knew that she got nailed cold when she was pushing heroin in the laundry room at Boys' Town, but I'm willing to give anyone the benefit of the doubt - especially when she's as crazy-looking as Mary-Belle."
