"Do you think I am standing here, making this up as I go? I am sorry to disillusion you. I am not Robin Williams. I am the king of the pen"

In this quote, Mitch Hedberg is humorously addressing an audience member who may have doubted the credibility of his efficiency. He makes a reference to star and comedian Robin Williams who was known for his improvisational abilities, implying that he himself is not making things up on the area. He then establishes himself as someone who thoroughly crafts their material with the title "king of the pen," further highlighting his dedication to his craft.
