pfft the Klingons stomped all over the Cardassians!
the Cardassians have trouble controlling their bowels at the mere mention of a Klingon battlecruiser.
. Really? I think that the Klingons were too busy chasing after sensor ghost, holograms and generally getting outwitted to cause any bowel loosening. (not that the Cardassians were actually scared by the Klingons)
three words: surprise attack and cloaks. That's how the Klingons won the war (and helped to start the Dominion war)
