Did anyone notice that when Ms. Cartman was putting up the Halloween decorations after the 2 zombies started to eat the passerby in the background. During the attack Ms. Cartman started to sing a Christmas carol. It was a bit hard to hear because of the screaming in the background. It sounded alot like "Jingle Bells" or something else. I'm not sure, I'll have to review the tape.
Also, right before Chef comes into the Doctor's office the patient is sitting on the table with Doc crouched over him and the patient turned his head and coughed. Don't bash me if this has been posted before.
