I know the first episode without one was O.R. from season 3, but was QUO VADLIS CAPTAIN CHANDLER? from season 4 the next one?
O wait, I just remembered; it wasn't. it was season 4s THE BUS and QUO VADLIS CAPTAIN CHANDLER? also from season 4 was the 3rd one. (it was also the first one where Radars real name was first mentioned)
