The Replacement - S5-E3

Trivia: In the episode 'The Replacement' Buffy asks what they're going to do with the 2 Xanders who then say 'Kill us both Spock'. This is a reference to an episode of Star Trek where Kirk ended up with an evil twin and Spock didn't know which one to kill, the real Kirk told Spock to kill them both so Spock killed the other one.

The Replacement - S5-E3

Trivia: In the episode 'The Replacement' when Xander is trying to convince Willow that he is the real Xander, he does the Snoopy dance for her. Nicholas Brendon didn't know what the snoopy dance looked like and just attempted it after a brief description. He is now frequently asked to perform it at any fan conventions he attends.

When She Was Bad - S2-E1

Trivia: In the scene preceding the credits for the first episode of season 2 'When She Was Bad,' Buffy saves Xander and Willow from a vampire, she then says 'Hi guys, miss me?' This is addressed to Xander and Willow but is said straight into the camera and is also addressed to the fans who had waited a long time between the 1st season and the 2nd.

Chosen - S7-E22

Trivia: In the final episode when Buffy, Xander, and Willow are wandering off talking about shopping, Giles turns round and says "The Earth is definitely doomed!" This is a little tribute to the end of the episode 'The Harvest' when Buffy, Xander and Willow wander off talking nonsense and Giles turns round and says a similar thing.
