The crowd was pretty dead, it's kinda embarrassing how he has to fake a laugh once in a while just to tell people that that was the joke
Dave has always done that. Go back and watch "Killing Them Softly" He hits the mic against his thigh and laughs. He just does it more now it seems.
I will say this, each of these specials suffer from the same thing most Netflix standup specials do.....lack of editing. Each one of these could stand to lose 10-12 mins off of them and they'd be much funnier.
But it is what it is.
