These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Covered Up: A lingering criticism of Denis Leary is that he stole some of his early material (mainly smoking/cancer related material) from Hicks.
Completely Missing the Point: Pretty much every time that Garth Ennis quoted or referenced Bill Hicks in the pages of Preacher, as Ennis was fond of using Hicks' material to mock people Ennis didn't like, all the while ignoring the fact that Custer and Cassidy were the type of people Hicks routinely mocked in his stand-up.
Crosses the Line Twice: Most of his act, but none more so than when he brings out lolicon-loving, sex maniacal, Anti Christ wannabe 'Goatboy', or 'Beelzebozo, The Clown from Hell.'
The Rush Limbaugh routine doesn't so much cross the line twice, as perpetually accelerate back and forth over the line in a giant circle. Vulgar Humor doesn't even begin to cover the first line.
Jokes in 1988 about coming back around 1994 with a smoking-related illness, a tracheotomy and a voicebox: "Y'all were right, smoking's bad!"For the curious Hicks died in February of 1994 of pancreatic cancer that, by the time it was discovered, had already metastasized to his liver. Smokers are more prone to various pancreatic cancers.
Hicks' rants about the first Persian Gulf War applied equally well to the second, right down to the name of the president. (Although the "tell me when, Lord" portion may be more a "Funny Aneurysm" Moment in the light of actual reports of W crediting his war motives to divine inspiration...)
Garth Ennis famously tried to shoehorn numerous references to Hicks in his comic series Preacher, even though a good amount of the series (most notably the anti-religious themes) directly contradict Hicks' own views on religion (Hicks believed in the existence of God and the usage of psychedelic substances to achieve closeness to God, whereas Ennis and Preacher were violently anti-religion and ended with the main character having God assassinated by a rogue angel).
To be fair, though, while Hicks was definitely a theist, he was extremely opposed to existing organised religions (especially Christianity) and said on Rant in E-Minor that it was humans' role to create a new religion.
