You wish you knew

[Nightmare85]

Hello mates,
Let's say someone asks me, "Who are you?", and my answer would be:
You wish you knew!
Would this be correct?
Or did I have to say something like:
You wish you knew it!
You wish you knew this!
You wish you knew that!

The first sentence (of the four) sounds incomplete to me.
The long version would be:
You wish you knew who I am!
I can understand that we can make either it, or this, or that out of who I am.
But just leaving it out?

Cheers!

Hi, Nightmare!

The long version would be:
You wish you knew who I am was!

You wish you knew who I am was!!

'who I am' is not hypothetical; you do not want to backshift tense here.

You wish you knew!

It is okay to use 'know' intransitively, but what does your sentence mean? Also, what is the exclamation mark at the end of the sence in aid of?

This a very strange answer to a simple question. Why on earth would you say this and what do you mean?

Hi,
The "!" just emphasizes the sentence, so its use is not that necessary.
The answer is if you don't want to give away your real identity.

Anyway, even if its sense is not that understandable, I would like to know if it's grammatically correct.

So, You wish you knew. (no matter if "." or "!") is already okay?

Well, in order to make more sense, we can change the topic.

P1: Will Argentina win the FIFA World Cup 2010?
P2: I wish I knew.
Grammatically seen, it should be the same...
(If the main sentence is correct, this one should be correct too.)

Cheers!

P1: Will Argentina win the FIFA World Cup 2010?
P2: I wish I knew.

This is fine, grammatically.

Penalty kick for hand play for Germany! They missed it, lol.

None of these sound right. If you need to give a rude answer, try:

A: "Who are you?"
B1: "Wouldn't you like to know!"
B2: "Who wants to know?" (ie. "Who are you, if it comes to that?")

Thanks, guys.

Raymott, okay, building example sentences is one of my big weak points.
Please, check this:
P1: Will Argentina win the FIFA World Cup 2010?
P2: I wish I knew.
(Of course we could also say, "You wish you knew.")

bertietheblue says it is correct, so we don't need to write:
You wish you knew it.
You wish you knew that.
You wish you knew this.

Do you agree?

Cheers!
