I think there's a little confusion between humor and 'gross' passing for humor. That's kind of regrettable, because they aren't the same thing.

In this quote, Bob Newhart is commenting on the evolution of humor in contemporary comedy, pointing out a growing confusion between what constitutes true humor and what some people mistakenly see as funny—namely, "gross" humor. He suggests that gross humor, often based on shock, crudeness, or bodily functions, is sometimes passed off as humor, but it lacks the depth and sophistication that real humor can have. Newhart implies that humor should be more than just a quick laugh; it should engage people thoughtfully rather than relying on vulgarity.

Newhart's mention of the confusion being "regrettable" suggests his disappointment in this shift. He clearly feels that the rise of gross humor has overshadowed more intelligent, nuanced comedy that requires skill in delivery, timing, and observation. By calling this confusion regrettable, Newhart is emphasizing his belief that humor should elevate conversation and provide something of value, rather than relying on shock tactics or simple offense.

As a comedian known for his subtle and deadpan style, Newhart’s approach to humor contrasts sharply with the crude humor that has become more popular in certain comedic circles. He often used understatement and dry wit to create humor that didn’t rely on sensationalism, highlighting his belief that the best humor is often found in the simplest, most relatable situations. His comment here reinforces his preference for a more intelligent, refined approach to comedy.

Ultimately, Newhart’s quote advocates for a return to thoughtful and engaging humor, where comedy is crafted with care, cleverness, and insight. He believes that while shock value can create a reaction, it doesn’t match the lasting power of humor that makes people think and laugh at the same time. By distinguishing between gross humor and true wit, Newhart encourages a more meaningful and intelligent approach to comedy.
