In a Bing! Bang! Bong!
When heads go ‘Dong! ’
And the ref says ‘No foul! ’
But he could be wrong.

There's a Bong! Bang! Bing!
When bells go ‘Ping! ’
As you just finish this round.
Saved - yet still in the ring!

In a Bong! Bing! Bang!
When fists go ‘Clang! ’
Can't quite avoid 'em when they do
Along with that painful pang!

So it’s
Bing! Bang! Bong!
Heads go ‘Dong! ’
Bong! Bang! Bing!
Bells go ‘Ping! ’
Bong! Bing! Bang!
Fists go ‘Clang! ’

A nasty place to hang…
Come in fresh and strong,
Leave it weak and hurting.
Better Know your ‘sweet science’
in a Bing! Bang! Bing! Bang! Bong!
