Does Dane Cook write his own jokes?

Dane Cook has been accused of joke theft on multiple occasions throughout his career. In 2010, a compilation video titled "Dane Cook Joke Thefts" appeared on YouTube, highlighting similarities between Cook's jokes and those of comedians Louis C.K., George Carlin, and others.

While Cook has maintained that he creates original material, many comedians and comedy fans dispute this claim. The negative attention this has brought led to a significant decline in his popularity.
