[Henry, the dog who is never ever off the couch, whimpers.]
Johnny: [Talking to Henry, while typing on the typewriter.] Sorry. Didn't mean to disturb you. Acting kinda uppity aren't you? I may put you in the script. Yeah. A dog that does nothing. [Henry whimpers.] Just sits there. People like that, y'know. A schleppy dog. You'll schlep out on stage and schleep on the couch. Dumb dog! [Henry whimpers.] Making me feel guilty. Why don't you howl or something?
When Roy is electrocuted and falls from the roof, after Karen uses the defibrillator paddles on Roy, she lifts both paddles, looks at the EKG monitor and says "He's converted." How exactly could Karen have known that he's converted? It's impossible for the EKG monitor to show anything at all. Either the defib paddles have be in contact with Roy's body for the “quick-look” to get a reading, which they weren't, or the ECG electrode discs have to be on Roy's chest connecting him to the EKG monitor, and they weren't. As an aside, just watching Marco having problems attaching the air mask, and quickly glancing up towards the camera frustrated, then giving up is priceless.
