YES! They do! I googled this and was happy to find this page. It’s SO clear they ripped of Rachel to create a Penny.
First off, they talk a like. They have the same humour, and same mannerisms. But let’s get down to how they really are the same — hot chick moves in across the hall from geeky male character.
They BOTH do a Vegas wedding in each show.
Rachel and Penny start as waitresses and become a success They both have a box of Ross/Leonard’s stuff from when they dated.
Not to mention both shows have a song about a cat lol
this is a total rip off. Penny even has the same lines said in the same ways as Rachel
