Use String#split to split the poem into lines. Then iterate from last
line to first line, outputting each line.

The same as above, but also use String#split to divide each line into words.
When outputting each line, iterate over the words in the line from
last word to first word.

The same as 2, but using String#reverse to output each word.

Take a look at the String documentation, in particular:

http://www.ruby-doc.org/core-1.9.2/String.html#method-i-split

Let us know how you progress.
