The text of the poem follows:

       <>!*''#

       !*=@$_
       %*<>~#4

The poem can only be appreciated by reading
it aloud, to wit:

       Waka waka bang splat tick tick hash,
       Caret quote back-tick dollar dollar dash,
       Bang splat equal at dollar under-score,
       Percent splat waka waka tilde number four,
       Ampersand bracket bracket dot dot slash,
       Vertical-bar curly-bracket comma comma
       CRASH.
