Dane Cook left the majority of the audience members laughing during a performance at the Frank Erwin Center this past Thursday.

The performance, a part of Cook’s Isolated Incident Global Thermal Comedy tour, used Cook’s observational humor to explore relationships, the differences between men and women and sex.

Most of the material came from the “ISolated INcident” album. However, Cook did perform new material including a not-so-politically-correct joke about the word retard and new material about masturbation.

The later ignited a series of “ews” from the audience, which caused Cook to admit that he had gone too far.

The show began with openers Al Del Bene and Robert Kelley.

Del Bene’s hilarious performance focused on a major event in his own life: being an expectant father.

The highlight of Del Bene’s performance was his exploration of the power parents have over their children.

Del Bene used a cheap shot at Mormonism to demonstrate this point and said that he could make his child a Mormon and really screw him up.

Robert Kelley’s message was that people should not care about what others think because when they reach a certain age, other people’s opinions will not matter.

Although his message was wise, the comedy he used to create this message was distasteful. At one point, Kelley resorted to a fart joke to get this message across.

Apparently, Kelley, who is middle-aged, has stopped caring what people think to the extent that he can recall an instance in which he farted in a baby’s face without any expressing any remorse.

The show ended with a surprise encore by Cook in which he recalled a disturbing email he received after his parents’ deaths. The email had said that Cook’s parents died to get away from his horrible comedy routines.

Cook said that he used the email to perform his best for his fans because seeing his fans laughter helped him get through both his parents’ battles with cancer and their deaths.

The encore showed a more emotional side to Cook, which was a refreshing ending to a comedy routine containing mostly sexual content.
