What is that smell? That smell, Bob, is our s**t. Focker flus...
Bob Banks: What is that smell?
Jack Byrnes: That smell, Bob, is our shit. Focker flushed the toilet in the den so the septic tank overflowed.
Greg Focker: I told you, Jack, it wasn't me, it was Jinx.
Jack Byrnes: FOCKER, I'm not gonna tell you again. Jinx cannot flush the toilet. He's a cat for Christ sakes!
Larry: The animal doesn't even have thumbs, Focker.
