Spanish Pensando en la inmortalidad del cangrejoThinking about the immortality of the crab.

A Spanish idiom about daydreaming. The phrase is usually a humorous way of saying that one was not sitting idly, but engaged constructively in contemplation or letting one's mind wander. The phrase is usually used to express that an individual was daydreaming, "When I have nothing to do I think about the immortality of the crab" (Cuando no tengo nada que hacer, pienso en la inmortalidad del cangrejo). It is also used to wake someone from a daydream; "are you thinking about the immortality of the crab?" (¿Estás pensando en la inmortalidad del cangrejo?)
