Other mistake: Amber states that Chase has a cat, even though in several other episodes Chase says he doesn't have a cat and wouldn't let Cameron get one because he hates cats. (00:16:10)
Continuity mistake: During the scene in which House is offering up liquor-flavored ice cream he sets the containers in a row down the table 1-2-3-4-5. He then puts spoons in the three containers closet to Foreman, 1-2-3. The shot changes and before anyone touches the spoons they are now in containers 1, 2, and 4.
Answer: It comes from the phrase "Everything but the kitchen sink." He's saying that House has thought of "everything but the kitchen sink."
