Fish biscuit
From YTMND
Fish biscuit is a fad based on a line from an episode of Lost in which the character Sawyer, being held prisoner in a cage, figures out how to work some mechanisms in the cage which delivers to him a biscuit shaped like a fish. One of his imprisoners, Tom, walks up to the cage at that point and says, "Hey, you got yourself a fish biscuit. How'd you do that?" The fad incorporates this line, and occasionally some other dialogue, including Tom's observation that it "only took the bears two hours" to figure out the same thing.
