Numerous ad-libs were included in the final cut. Such unscripted bits are when Willow runs off the stage terrified and when Xander cries "Redrum! Redrum!"
During a panel discussion that was a DVD extra for the Season 7 DVDs, Joss Whedon said that after finished filming, they got a note from the network asking for the talent-show scene from Oedipus to be removed. The note said: "We realize that it's Shakespeare, but does he have to talk about sleeping with his mother?" The ancient Greek play Oedipus Rex was actually written by the Athenian playwright Sophocles about two thousand years before Shakespeare was born.
On the original airing, the closing credit sequence was split-screened with a scene in which Buffy, Willow, and Xander perform a scene from the play Oedipus Rex. This scene was excluded in repeat airings until the series left The WB Network. It is included in the DVD Collections, and in present television reruns.
Xander plays Oedipus, Buffy plays Jocasta, and Willow plays the priest of Zeus.
