My New Role - S8-E7
Audio problem: Season 8, episode 7 "My New Role": Before the opening credits, JD taps a pencil against a cup, and other various devices in the hospital start making a song. At the end of this song, the Janitor can be seen playing the bongo. The rhythm of his hands do not match the rhythm of the bongo sounds at all. After the song ends, JD turns to the Janitor, who is again playing the bongo. This time, however, his rhythm of his hands do match up with the rhythm of the bongo sounds.
My Absence - S8-E9
