Will Colbert (Brad Pitt): formerly overweight friend of Monica from Ross's class in high school with a grudge against Rachel. Monica invites him over for Thanksgiving dinner in "The One with the Rumor" (airdate November 22, 2001; Season 8, No. 9). Will has lost 150 pounds and now looks great—which makes Phoebe flirt with him. Here they find out that Will hates Rachel due to all the bullying he had suffered at her hands in high school and had co-founded the "I Hate Rachel Green Club" with Ross and spread rumors about her being a hermaphrodite. He is last seen looking bemused but amused when Joey enters the room wearing Phoebe's maternity pants (under the deluded belief that he would need to change into a new pair of pants to achieve his goal of eating an entire turkey all by himself). Pitt was married to Jennifer Aniston in real life at the time, and his given name is in fact "William".
