The suits of armour use the wackiest Dancing Pants shenanigans while fighting Those Wacky Nazis. A recurring visual gag is the suits removing limbs or helmets to shake out accumulated bullets.
Highlights include one suit of armor taking off his leg, shaking the bullets out of it, then hopping over on one leg and beating a Nazi over the head with it, and a disembodied pair of legs literally kicking a Nazi's ass. Repeatedly.
One somehow ends up seated in a walking pair of legs, shouting all the while to be released.
The look on the Colonel's face when the executioner comes for him.
"Would you like to be turned into a small white rabbit?" It's actually a very real threat!
