"I would say that fifty percent of my show is killer comedy"

Davy Jones is referring to the quality of his show when he says "I would say that fifty percent of my program is killer funny". This suggests that he is positive in the comedic content of his program and believes that half of it is of a high quality. It could also be translated as him being simple and not wanting to overemphasize the quality of his program. He might be implying that the other half of his show is not as strong, however still amusing. This quote might also be viewed as a difficulty to his audience, as he is asking to evaluate on their own the quality of his program. It is a testimony to his confidence in his comical abilities that he is willing to put his show to the test.
