Having opted out of college, Xander (Nicholas Brendon) takes a job at the local student pub as a bartender. His first night is a humiliating one with snobby student Colm (Eric Matheny) antagonizing him "like a Bad Will Hunting." Colm and his buddies then proceed to guzzle case after case of Black Frost beer. Meanwhile, Buffy (Sarah Michelle Gellar), still pining over Parker (Adam Kaufman), decides to come to the pub. She bumps into Riley (Marc Blucas), who disparages Parker's slimey behavior toward women. Feeling even worse, Buffy joins Colm and his friends in downing the Black Forest beer. Soon the group has reverted to their baser instincts, literally, as the beer was prepared by the pub owner using warlock magic. Soon, they've all gone Cro-Magnon, dragging girls into the Grotto -- the local student coffee bar -- with Buffy hunching away, grunting, "Parker, bad."
