Unfortunately there are people out there (a non-trivial number) who actually believe that kind of macho BS. Knowing that, Carlin's jokes don't hit the same.
I don't think that's a good argument. If I went this route, I would have to forgo Monty Python, Key & Peele, Mitchell and Webb, and god knows who else. There are always people believing this hyperbole, that's why it's funny in the first place.
But the good jokes either go extremely over the top, or actually have a joke part. The quoted one just repeats a thing that people believe. Reading it, I can't tell if it's supposed to be mocking the position, or is he a genuine grumpy guy complaining about kids these days and their cleaning.
I'm sure you can find the whole sketch on Youtube. I can only recommend watching it, unless you are allergic to swearwords - there are lots of those. Look for [George Carlin Germs]. But I guess the audience on HN generally knows how to figure it out by themselves.
