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?

Your logic is OK - and it does not ridicule the reasoning of others.
I observed that if one decides upon A, then the question is "why not B?"= and vice versa.
Assuming C as an answer - everything fits.
The above process of solving lasted seconds - first eliminating possibility of different status of A vs B - then getting a final confirmation while reading the last statement.
