When grading an open mic, I take several things into consideration: how supportive the room is, how much it costs to perform (money spent and time committed waiting/commuting) and the value of the time spent on stage. For experienced comics who hit several open mics each week, it's vital to find the shows that will help you grow. Simply put, there's no time to waste.

At Kingdom of Heaven, time is well spent. There are 10 spots, and each is picked in a random drawing. The creators/hosts John F. O'Donnell and Timmy Williams are quirky guys who always entertain (at times using a separate microphone off stage to tease each other). The system favors neighborhood locals and regulars: If you don't live nearby it can be a devastating blow to your evening to see that you won't be on the show. But don't worry -- the producers pay attention and if you keep coming back, you'll get stage time.

Each show is capped by a booked "Comedian of Merit," This is a good opportunity to observe the skill involved in performing a longer set. For the 10 randomly chosen comics, you'll get the chance to work on your material without having to make a down payment or fulfill a drink minimum. Kingdom of Heaven is a venue that wants comics to push themselves and take risks.

Too often comedy is an isolating endeavor: We come in, do our sets and leave. Even if you're not chosen to be part of the show that evening, Kingdom of Heaven is still a place to get ideas, network and enjoy the process of comedy creation. It's an open mic with the feel of an all-star underground comedy show.
