My wife prefers it since before we met, there was a woman she went to college with who looked like her and a lot of people confused them in classes together. Both were 5'6, similar build of being somewhat in shape with curvy bodies, short hair in a bob and glasses. According to my wife, the other woman had enough of being confused with my wife at the college and the two got into a catfight. It was broken up before a clear winner was determined, but she's always wanted a rematch to see who'd win.
There was another woman I worked with who looked like my wife and apparently lookalikes of my wife wanting to fight her because co-workers kept comparing her to my wife who no longer worked there. Kelly accepted, but the other woman backed down.
