Can you turn me on to some comedians?

My favorite comedians or style is kind of like the common sense apporach type ones

2 that first come to mind are Lewis Black and George Carlin.
There was another guy with red hair skinny white guy, can’t remember his name…..

I do not care the style too much but this gives you an idea of what I like…

Please do share your favorite stand-up comedians. Thanks.
