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 of the arm
Chorus:
  Never ever never trust a Klingon
  You will always regret it
  Never ever never trust a Klingon
  You will never forget it

Repeat chorus
