don't pay for something that's going to be useless to you soon.

[The Unintelligible]

I am all for commas, however, the citation states he and I are not always grammatically correct. It's based on the circumstance of whether the people are the subject or affected by the subject. In the original quote the picture is the subject and the people are the affected. So yes, me is correct and I is incorrect. However, in your new example "he and I" are the subject

Yeah man, you're wasting your time.

I think he knows this already, he just chooses to ignore to feign self-righteousness. Or he's really that dumb that he doesn't understand how he's wrong yet again.

Either way, don't really care. Just amazed at his stupidity and persistence.
