Lyrics:

The Klingon bastards flies around
Always ready for some war
They don't care about any rules at all
As long as they can kill some more
Evil barbarians without discipline
Unpredictable death machine

With their cloaking device they remain invisible
Until the time has come
To appear right ahead of us
And obliterate everyone
If you ever would give them a helping hand
You can be sure they'll chop off the arm
Never, ever, never trust a Klingon
You will always regret it
Never, ever, never trust a Klingon
You will never forget it
