The supposed "heavy" pipes that Archer is having a tough time carrying into the Ferengi ship that is looting Enterprise are clearly made out of foam since you can see on the side of one of them that some of the gray paint has shredded off.
Archer asks Tucker to get some Phase Pistols. Tucker says the Ferengi cleaned out the armory; however, the Ferengi ship where the goods are being stored is not even 10 meters from them at this point (Krem is making Archer transfer stuff from Enterprise to the Ferengi ship).
The Ferengis' gas bomb delivers a knock-out gas that renders all the crew members unconscious. However, at least one of Dr. Phlox's lab animals and Capt. Archer's dog Porthos are fully awake when the Ferengi come upon them.
