Correct, people comment bad jokes all the time. This is completely irrelevant as I didn't call him out for the bad joke. I made a bad joke in response to his bad joke.
I called him out when a number of people corrected his bad joke (including down voting him), and he tried to justify the bad joke with more bad jokes and deflections about how he just couldn't remember syntax and he has all this experience. It's a problem he has with admitting fault, not about his joke, but how in making the "joke" he tried to prove to people he didn't really make a mistake.
He did this on another post the same day when he claimed a link was paywalled. It wasn't, multiple people said it wasn't, and he insisted it was for him, only to later, after multiple back and fourths say that he has bad eyes and that the site needs to be made better. I bring this up, because he even brought it up here.
So again, I have no issue with bad jokes, I have no issues with bad programming. I have an issue with people who want to pretend like they are perfect and it's everyone else who is at fault.
