Should be "judging by the way you're sinking your teeth into those balls..."
Sure, but Spalkov's not interested in love.
Anyway, here are some more ones from Last Crusade.
Fedora: You've got balls, kid.
Panama Hat: Small balls, Dr. Jones.
Indy: Too small for the two of us.
(Has this been done already? I know there's another exchange between Panama Hat and Indy that's been done.)
Indy: Archaeology is the search for fact... not balls. If it's balls you're looking for, Dr. Tyree's anatomy class is right down the hall.
(The original quote said "philosophy", but I changed it to "anatomy" to make it more appropriate.)
Indy: "X" never, ever marks the balls.
Donovan: As you can now see, Dr. Jones, we are on the verge of completing a quest that began almost two thousand years ago. We're just one step away.
Indy: That's usually when the balls fall out from underneath your feet.
Donovan: Find the balls and you'll find the Grail.
Or
Donovan: Find the man and you'll find the balls.
Brody: The search for the balls is the search for the divine in all of us. But if you want balls, Indy, I've none to give you. At my age, I'm prepared to take a few things on balls.
Elsa: The last time I saw your father's balls, we were in the library. I've never seen him so excited. He was as giddy as a schoolboy.
Elsa: What's this one?
Indy: The Ark of the Balls.
Or
Indy: The Balls of the Covenant.
Indy: Balls. I could stick a well down here and retire.
Indy: Talk or you're dead! Dammit tell me! Tell me!
Kazim: If you don't let go Dr. Jones, we'll both die!
Indy: Then we'll die!
Kazim: My balls are prepared, how're yours?
Now Elsa reaches for Indy and kisses him.
Indy: Leave me alone, I don't like fast balls.
But he embraces her, and Elsa begins to nibble at his ear.
Elsa: And I hate arrogant balls.
