Текст песни The Fish

?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.Alice In Videoland - The Fish - http://ru.motolyrics.com/alice-in-videoland/the-fish-lyrics.html

?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?
