Bewitched, Bothered And Bewildered

In which Xander is simply irresistible, Cordy is resistant, Oz is angry, Giles is jealous, and Buffy is a rat. (Exhibit D in the 'Xander is Hot' debate)

Official back-of-box synopsis:

When Cordelia succumbs to peer pressure and breaks up with Xander on Valentine's Day, he convinces a witch to put a spell on her. But the spell backfires, and soon all the women in Sunnydale begin to see Xander in a whole new light.

From the old WB Buffy website:

EVERYONE LOVES XANDER -- When Cordelia succumbs to peer pressure and breaks off her tryst with Xander, on Valentine's Day, he convinces a witch to put a spell on Cordelia which will make her fall in love with him. But when the spell backfires, the women in Sunnydale, except Cordelia, and including Buffy and Drusilla begin to see Xander in a whole new light.
