The poem can only be appreciated by reading it aloud, as follows:

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,
Pipe curly-bracket, comma comma CRASH.
