Chandler (Matthew Perry) and Ross (David Schwimmer) have a run-in with a pair of bullies at Central Perk -- only to join forces with their tormentors when another bully horns in. Monica's (Courteney Cox) eccentric methods of stock investment (based upon her initials) come a cropper, forcing her to take a humiliating job at a "1950s" diner. And Phoebe's (Lisa Kudrow) efforts to meet her birth father yield unexpected results. ~ Hal Erickson, Rovi
