‘First the fish must be caught.’   That is easy: a baby I think could have caught it.   ‘Next, the fish must be bought.’   That is easy: a penny, I think, would have bought it.      ‘Now cook me the fish!’   That is easy, and will not take more    than a minute.   ‘Let it lie in a dish!’   That is easy, because it already is in it.      ‘Bring it here! Let me sup!’   It is easy to set such a dish on the table.   ‘Take the dish-cover up!’   Ah, that is so hard that I fear I’m unable!      For it holds like a glue-   Holds the lid to the dish, while it lies in the middle:   Which is easiest to do,   Un-dish-cover the fish, or dishcover the riddle?
