<human>: My brother lies about a lot, but as of late he has taken it to a new level of idiocy.

Before the college issue I now that he has lied about working with me at Wal-Mart and lied about holding down a job at a gas station. I've never seen him work a single minute at either place.

Out of exasperation my mom let this pass and refused to tell my dad, who was being mentally and physically drained by my brothers bullshit. WE finally got him, his wife and his fucking kid out of the house and this comes up.

Two months later and I have to talk to a financial aid counselor about why my loan was being held up and she breaks the news to me that it was being held up because I had put down my brother as a sibling who was attending school when he wasn't.

He told my mom that he was attending classes from 8-12, but it turns out that he isn't going at all. 

I don't know what to do. I love him, but he is literally becoming an intolerable person. If I confront him I know he will get defensive and aggressive. He refuses to back down on anything. I'm afraid to tell my dad about it. I don't want him to have to deal with this anymore. He thinks that his son is becoming an engineer and will soon be supporting his family with a decent job. 

What's worse is that his wife has told me that she works a lot to help put his thick ass through school. His wife and his kid are counting on him to provide for them and he is at home playing video games with his thumb up his ass.

What do I do?

Could you distill the essence of the text into 1-3 sentences?
