When House is lighting a cigar with the $100 bill you can see the bill says "Motion Picture Use Only" where a real bill would say "The United States of America."
At 32:03, House is starting to use the paddles on the patient while Dr Foreman is still touching the patient's chest. Dr Adams grabs Dr Foreman's arm to pull his hand away and yells out, "Wait! Dr Bruen!" There is no Dr Bruen in the room or the scene.
