I recently viewed a Louis CK 'stand-up' on Youtube.
Except this 'stand-up' was not a comedy stand-up.
He gets me every time, except he was not looking for laughs.
WHAT THE HELL IS A STAND-UP COMEDIAN DOING A STAND-UP AND NOT SEEKING LAUGHS?
I do not know and when I found this exposition I was given no background with regard to this riff.
