Season Three

Dead Man's Party
Xander rambles about everyone's yen to not discuss what's happened. His remedy? "...so let's just shut up and dance."

Faith, Hope & Trick
Cordelia's grooving to the beat, hands in the air sometimes a la Buffy while Xander is "working his outer shirt." He's comfortably dressed, comfortable with his Cordy 'ship, and comfortably dressed. I'd say he had a happy.

Homecoming
Xander and Willow had a memorable dance to Lisa Loeb's song "How." It led to the 'fluke' and therefore it gave some viewers a happy. Another dance of Xander's is his lack thereof (and Willow's as well) at the actual Homecoming Dance.
