When did you hate Penny the most ?

Recently I can’t watch the show because of how bad Penny treats Leonard in it and I am puzzled to see people who actually like that, two episodes come to mind that I wanted to punch her really was the one when she told him he stopped trying to impress her and second was when they hang out as friends and she ditched him for cuter guy then interrupted him when the guy left, not to mention all the times she took Sheldon side, Penny was not a good person
