Here's an article citing Amy Schumer stealing jokes. Sorry to beat the dead horse here, but I went looking for some actual examples and figured I'd share.

Based on what some of you guys were saying I was expecting it to be FAR worse. A lot of them are examples from movies and tv sketches that she shares writing credit for (I'm assuming she doesn't write everything), and even then some of those are a bit of a stretch. Every theme in comedy from "men are lazy" to "women are crazy" has some overlap from time to time. It's like being mad that a band uses a familiar hook in a song... it's impossible to totally avoid.
