Pete (Jon Favreau) enters a grueling "ultimate fight," leading to a lot of hurt and a fateful decision by Monica (Courteney Cox). Ross' (David Schwimmer) new date Bonnie (Christine Taylor) once had a hair problem -- mainly, she didn't have any. Chandler's (Matthew Perry) new boss gives a whole new meaning to the word forceful. And yes, those two guys in the park are just who you think they are. ~ Hal Erickson, Rovi
