You meet three blonde women, A, B, and C. Each of them is either a knight or a liar. Exactly one of them is Elle Woods.
A:I am Elle Woods.
B:I am Elle Woods.
C:At least two of us are liars.
What are A, B, and C, and who is Elle Woods?

Logical Outcome (Spoiler) by Ady TZIDON)
I agree with Ady's answer, but not his logic. You cannot determine that A and B are false without looking at statement C. It is possible that A is true and B is false, or vice versa.
----------------------------------------------------------
Correct Logic:
If C is a liar then there is at most one liar, so A and B are both telling the truth. But this is a contradiction, so C is telling the truth. Then there are at least two liars, and they must be A and B, so A and B are not Elle Woods, so C must be Elle Woods.
