Amy Schumer routinely steals jokes. There's a compilation on YouTube. She does one of Ellen's famous bits on Ellen, to her face without crediting her/saying it's an homage. And you can tell DeGeneres just wants to rip her fat face off but can't in front of the camera and studio audience. Schumer's shit will catch up with her someday. She's offending too many people with more juice than her, and she can't keep stealing forever without someone calling her on it or suing.
