Since I've apparently already been labeled, I guess I needn't fear the results of weighing in.
I'm not a humorless man, in fact, people who know me would say that I've got a very good sense of humor. Having said that, what is it that is humorous or appealing about this song? Is it the repeated use of profanity? Is it the repeated blanket accusation using unnecessary profanity? It's not even a clever song. Everyone is greedy and lazy so I can self-righteously judge them and issue a blanket insult using profanity? The premise isn't even true and perhaps I'm wrong, but I doubt that the song was shooting for irony.
You might have already guessed that I'm not a fan of profanity. It's intentional use in this type of circumstance is one of the lowest forms of cheap humor. I don't think it should have any kind of place in this forum but that's just this man's opinion and the song writer has already told you what I am.
