Which leads you to wonder about the venue, and/or what they know about him. Surely this isn't a new thing, where some "underground" comic has a bunch of friends and friends of friends buy up tickets and show up and show their support, regardless of how much the person sucks. I mean, they can't seriously think that he's good because he sold so many tickets, can they? I don't really know what the explanation is; but I just can't see them thinking he's good based on ticket sales alone.
And yeah, I don't know what he thinks he's doing trying to do an entire show for his "big break". I would think you would want a 10-minute slot, as that's a lot easier to handle and a lot less can theoretically go wrong in 10 minutes as opposed to an hour or more. He's going to be pressed for material anyway, as has been noted in this thread.
But then again, I suppose thinking that way requires some measure of modesty in how you regard yourself.
