First off......Joe Rogan is a comedian?
Seriously, I had NO fucking idea. I only knew of him from that shitty reality show, and recently from The UFC commentating.
Comedian, huh?

No fucking clue.......

Second......did he just fucking start that whole scene in the middle of Carlos' show?
If so, not fucking cool at all. There's a time and a place for that shit, in the middle of someone else's routine is not it.
Third, who fucking cares? This stealing shit has been going on forever. In happens in music, movies, to....you fucking name it. EVERYTHING HAS BEEN DONE to some degree, so being original is tough.
Is it right? No, but it happens. Obviously it's working for Carlos more than it is for the people who supposedly came up with it originally, since he's the one who's now famous......
If it bothers them that much, improve your fucking routines, and may the best comedian get the laughs......
