Calculating $E[X^2Y^2]$ given $E[X^2]$, $E[Y^2]$, $E[X]$, $E[Y]$, and that $X$, $Y$ are Gaussian.
Thanks unknown. Yes, it was a mistake. And thanks Gjergji for the roll-back.

Excellent! Thank you. In the paper I am reading, it does hold that vector (X,Y) is Gaussian, so that was a hidden assumption in my question.

Thanks for the example Michael. I edited the question to add more conditions.

Hmm... the variables $X$ and $Y$ are Gaussian, although I can't see this helping...
