Hit you with what? Good comedians so you can just call them shit and pretend you won the argument? I'm not going to do your heavy lifting for you, if you want better comedy than the Big Bang Theory and Kevin Hart then put some fucking effort in.
Or you're just looking in the wrong places for your comedy. Because what you just said is objectively not true. Not even a little bit. Sure there are some awful comedians out there who copy material from others. But those kinds of people existed long before stand-up was even a thing.
