Lol, okay:
Oh wait a second, I somehow didn't see you first answer correctly. You didn't do some editing, did you? :)

1. Okay, that one's right.
2. He is lying. Only some of the things he tell's you are true.
3. Correct.
4. "What is the answer to this question?' This is.
5. While retarded, you might skip around that and give the average length of a duck, as "difference" might be interpreted that way.
6. I'm fairly sure about this one: It's not a paradox, or false, or true because....... it hasn't made any claim. Reason being, "This statement is false" is self-referencing; if we substitute "This statement" with the statement we get "This statement is false is false." Again, we replace "This statement" for the statement, and again and again. When are we going going to find the claim? Never, it isnt making one.
End Spoilers.
