I am a former stand-up comedian.

I have to say, that line, "Neanderthal, dark and handsome'

Not joking at all..... That is fully professional comedy there. Fully.

If you can produce stuff like that regularly, you can get work as a comedy writer.

Not joking. I was offered to write comedy for a major Hollywood animated film...not too too long ago. So, while I may not be the best comedian out there, I can recognize top level stuff. And that line is top line stuff.
