"some maybe-sexy hugging". Excuse me?
"I told her that Darth Vader was our father, and that I had to go face him."
I'm sorry, the thing of him thinking his mom was hot was creepy. The whole sister thing was way worse, but that last bit... I don't even know what to say to that. This guy must be in-bred. There's no other way to explain it.
He's like this guy I went to high school with, who's dad was literally his grandfather also, and his mom was his own sister. It was insane. (And yes, that is biologically possible, as proven by his dad/grandpa, and his sister/mom).
Edit- Wow. I just got the joke. I feel pretty retarded. That's what I get for not being a Star Wars fan.
