More snark from Spike:
"Yeah, I could do that but I'm paralyzed with not caring very much."
Season 5, Episode 11 -
Triangle.
This was another funny episode by Jane Espenson. This was the episode with Anya's old boyfriend, Olaf the Troll.
We also have Spike, who, a few episodes prior, has finally realized that he loves the Slayer. But, being a vampire, he really doesn't quite understanding how to deal with it.
