Comedians have a right to....
*....good staging, lights and sound.
*....an attentive audience.
*....perform at a properly promoted show. NOT a bringer.
*....stage time because they support your open mic night and NOT because they took a certain comedy class run by a bartender.
*....an introduction made by an MC who cares!
*....do what they think is funny.
~There's more but these will help you kick off your open mic night with total positive energy.
