season two episode "The One Where Ross Finds Out", in which an idle and unemployed Monica is temporarily acting as Chandler's personal trainer. However, Silveri's suggestion was initially vetoed by the other writers, who felt that it was simply too soon to introduce another main couple to Friends having just recently paired off Ross and Rachel. Following Ross and Rachel's break up in season three, the writers felt that the timing was just about right to officially introduce Monica and Chandler as a couple, deciding that Friends "can't simply rest on this one [Ross and Rachel] relationship", while believing that Monica and Chandler's would ultimately provide a fun opportunity for the writers to explore brand new storylines.

Monica and Chandler's relationship is the antithesis of Ross and Rachel's because it remained "healthy and strong until the series ended", while the
