* Those pesky severed heads! They always tip over.
** West trying to get Hill's head to say something after said decapitation and reanimation:
--->'''Hill:''' You...
--->'''West:''' Ok doctor, that's good, "You..."
--->'''Hill:''' BASTARD!
* Herbert repeatedly breaking pencils just to interrupt Hill's lecture.
** "Mr. West, I suggest you get yourself a pen!"
* "Cat dead. Details later."
* West absently tapping Hill's head with a pencil as he's waiting for the serum to take effect.
* Hill trying to manipulate his body to the fridge and getting annoyed by its fumbling.
* Dr. Hill's muffled, annoyed "Of course it's me!" delivered from inside the bag his body is carrying him around in.
* The security guard's bemused reaction to seeing a headless body fall down at his feet, get up, and run back into the fray.
* The scene where West and Cain try to kill a re-animated cat. Especially at the end when Cain chucks the cat at the wall.
** The cat being re-dedified, West immediately shouts "LOOK OUT!", making Dan wheel around in terror and West bust out laughing.
* "Make a note, Dan! Tissue rejection!" As if Dan, currently fighting half a dozen zombies, is in a position to make a note about anything.
