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.
Question: In one episode (I think it's My Balancing Act) Dr Kelso is trying to scare the interns, so he pulls his face off and 'becomes' a guy with crazy ginger hair and a very annoying loud voice. I'm a Brit so that's maybe why I don't recognise this guy. Is he supposed to be someone famous?
