Hahaha you have to love the first question out of the gate is effectively, "brah, what's with all the dick songs?"

@aagabriel believe it or not the answer is a bit more complex than one would expect my response to be. I suppose there is the answer from LP the jester and LP the deep thinker.

There is the obvious side of it where taboo topics mixed with context and wordplay are absolutely hilarious. In fact, it checks off a number boxes on some of the basics around the psychology of the eight things which cause laughter in humans (the most significant being release). Besides the things we all experience or fantasize about in quiet shame are hilarious with the right word play and context.

Then there is the side of LP the deep thinker. I think we are all conditioned by society to seek approval and adopt forced cultural norms with a clear intent to destroy individualism. The most obvious straight jacket placed on every human is the idea of "bad" words, "good" words and "taboo" topics. When a society or power structure censors or limits the words and topics an individual can use to express themselves or speak about - this is the most deceitful and nefarious form of control. Yet look at how this is conditioned and reinforced into each of us every day. I think to a large degree the deep thinker in me purposely seeks this out and broadcasts these "smutty, silly songs" to remove the arbitrary social stigma and power, remind individuals words are just that and none should be forbidden, and to do so with humor because even the ugliest truths are more easily accepted with a humorous edge. It is the essence of satire.

I guess Voltaire was more significant than I let on.
