Season 2 Episode 10 Despite living in denial after having her heart broken by Ross' relationship with Julie, this was the episode when Rachel's near-obsession with Ross came full circle. Hilariously, viewers met Russ, Ross' leather-jacket wearing doppelgänger in one of the funniest sort-of-cameos in the show's full run. Inevitably, Ross thinks Russ is a jerk, failing to see the similarities that it takes Rachel way to long to notice herself. Sadly, Russ doesn't last as she comes to her senses, robbing fans of more Ross/Russ interaction in future episodes. The same episode saw a lesson about people trying to change their partners, as Monica attempted to "fix" Fun Bobby, only to discover that his alcoholism was the only thing making him any fun.
